Hello

I am having the same problem as the OP, but I don't quite get the "sweeping" solution? Can somebody please explain that to a non-techie? Sorry for being stupid Sad

Your help is much appreciated!

Click "wallet" in the top menu bar, then move your cursor down to the "private keys" entry in the dropdown list that opens, then move it to the "sweep" entry in the second dropdown list that opens, then click your mouse.

Afterwards this window should open.

Enter a list of all the private keys you want to sweep into the window, then click the "sweep" button.

Yes, a new wallet on the same computer, I did the sweeping thing and have my coins back.

But am still trying to understand what happened to the old wallet, so it will not happen again, and also cause I need to understand

I'm glad you got your coins back. Unfortunately I'm not sure why the old wallet wouldn't sync. Maybe the wallet file had some small corruption in it that stopped electrum syncing.

It worked, but the weird thing is that I could open a new wallet on the same computer that is synchronizing, the older one is still stuck..
Thank you do much for your help,
and if you have any idea how to unstuck my old wallet I will be happy to hear about it.

Do you mean you could open a new electrum wallet on the same computer? If that's what you mean and you now have the private keys from your old wallet you could either import them into your new wallet, or sweep them into it. These two links explain how to do it.

All are set to 0..

these are public addresses, right?
should i screen shot it and paste here?

btw, my electrum-LTC portable wallet is working properly.

It doesn't matter if they are all set to zero. That just means the wallet's probably not synced. It doesn't need to be synced to get the private keys for those addresses.

Search for each of them in this website.

https://blockchain.info/

Right click and save the private key for each address that the website shows has cons in it. You can import those private keys into some other wallet software to spend the coins.

The only transaction with coins is the one I can't see in my wallet cause its not synchronizing, its there but with no coins and defined as "unknown", I can't right click it, is there any other way to find its private key?

Try clicking "wallet" in the menu bar, then "addresses" in the list that appears. A new tab should open showing the addresses in your wallet.

Before deleting, is there a different wallet software that will allow me to load the seed created by electrum?

There's no other desktop wallet software that I know of that can load electrum seeds.

Don't delete your electrum wallet just yet. Right click each address in it that contains coins and click "private key" in the list that appears. Your wallet should then show you a private key that you can copy.

After you copy all the relevant private keys you can import or sweep them into some alternative wallet software.

I actually don't think its the the anti malware but this is the only new stuff that I can recall, other than that it worked with my win firewall (electrum is in whitelist) and avast.

I'm not sure what the problem is then.

You could try deleting the blockchain_headers file in your installed electrum wallet.

Copy this line of text.

%appdata%\Electrum

Click the windows start button, then paste the line of text into the search box that appears, then press your enter key to open the folder containing your electrum wallet's blockchain_headers file.

This is what the search box should look like after pasting the line of text into it.

Delete the blockchain_headers file, then start electrum and check if it syncs.

You ware too fast

thanks, still synchronizing tho a new header file was created

Turn off your firewall and antimalware to determine if that is the cause. If working then, turn on one at a time to see which is getting triggered and add an exception in settings for Electrum.

Already checked that, thanks.

Before deleting, is there a different wallet software that will allow me to load the seed created by electrum?

I removed new anti malware software I've recently installed - can't recall if the problem started after installing them, it was "bitdefender" and "malewarebytes"

I wouldn't run a wallet on a machine without anti malware software and a firewall. If you removed all such software I would quickly replace it with alternatives before doing anything else.

Most anti malware software and firewall software have a white list somewhere in their settings. If you add the electrum executable file to a white list it will allow it to connect to the internet.

I never did it, so quick question about it, all I need to get access to my wallet is the seed (12 words), right?

Yes all you need to access your wallet is the 12 seed words.

I have a back up of the history, is that mean I could reuse it on my new wallet? meaning that it will add the transaction description?

I have not tried backing up the history yet, so I can't advise about it.

It didn't helped, however an older wallet I used in the past - MultiBit is synchronizing properly.
is there a possibility that the antialwares introduced some changes to my system that are not allowing electrum to synchronize?

If I'll uninstall and reisntall electrum, could it help?

Didn't sync also with the portable version,
should I try deleting blockchain_headers anyway?
where would I find it?

If the portable version didn't sync either then I doubt deleting the blockchain_headers file from the installed version would help.

Is your firewall or antivirus software stopping your wallet connecting to the internet? Most of them have a list of blocked software in their settings.

By the way your 0.00388651 BTC payment to 1KWVdojogcq6FQACNYuhpuz52U6Nds2h3i shows on blockchain.info.

https://blockchain.info/address/1KWVdojogcq6FQACNYuhpuz52U6Nds2h3i

You are faster than me! I was just getting ready to paste it in here. At least the OP can see and know the coins are safe at that address.
