democrite,

If you want to start messing with your MultiBit folder, you must be careful with what you do and don't deleted.

These three items are safe to delete:

Code:

"multibit CHECKPOINT File"
"multibit SPVCHAIN File"
the "log" File folder

These critical items you must back up:

Code:

Every WALLET File
the "multibit-data" File folder

There are some other files in there too, they contain preferences and transaction notes you've added. They're not critical to back up, but there's no reason to delete them either; just leave them alone.

If I were you, I'd
1. close MultiBit
2. take a copy of the two critical items above, just in case (right-click & copy, then go to another folder e.g. My Documents, right-click & paste)
3. delete the three deletable items above
4. re-install the latest version of MultiBit (v0.5.18) from here: https://multibit.org/

What I can get with this process ??

Not much.
I think that the data from your user folder is broken. And a reinstall may not fix that (the uninstall may not delete the broken data, the new install will try to use it).
Saving your private key is a good idea, because whatever goes wrong, your money is safe. You should do that.

If you want to "save and restore", it works better / easier if you do that with (the correct) *.wallet file.

Thanks for this several suggestions and reply.

No, I am not it person

But I tried many thing and change nothing ...

I am sure that I must uninstall multibit and reinstall but I am scare to lost my money with this process ...

If I do :

- export key. My key will be save in my computer, right ?
- After I uninstall multibit
- After I reinstall multibit
- and for finish, I import my key in multibit.

Like this, I don't lost something about my btc's, right ?

What I can get with this process ??

Instead of importing your private keys, just backup your wallet.
try this:
Go to C:\Users\(user name)\AppData\Roaming\MultiBit
copy all data in that folder and uninstall multibit and delete this folder ► C:\Users\(user name)\AppData\Roaming\MultiBit
Now reinstal multibit and paste the content you copied at ► C:\Users\(user name)\AppData\Roaming\MultiBit It'll ask "file already exist replace?" Click Yes.
Now open multibit Wink

it'll synchronous to till date. This will help you.

I've had this same problem with MultiDoge, about one year ago. As they are quite similar, I'll share what I've done. Reinstall is not needed.

1. Stop MultiBit
2. Copy all the content of c:\Users\Your User\AppData\Roaming\MultiBit to (a newly created) c:\Users\Your User\AppData\Roaming\Multibit.Backup
3. Delete from c:\Users\Your User\AppData\Roaming\Multibiit all the files except multibit.wallet and multibit.properties
4. Start multibit and wait it to sync, it may take some time.

When you are convinced that everything is back to normal, you can delete that backup folder.

democrite,

There are two good suggestions by shorena and jim618 which you seem to be ignoring.

Meanwhile, you've responded to a possibly dangerous suggestion by Rude Boy. Exporting/importing private keys isn't necessarily a bad idea, but it's possibly dangerous if you don't know how to securely handle sensitive data, or if you don't know what Rude Boy means by "shred" (which has a very specific meaning—it doesn't mean delete). IOW, if you're not an IT person, I probably wouldn't follow Rude Boy's advice.

Please be careful....

probably democrite is already trying to (mentioned below)

Yes I already tried. My multibit it is in english language

but didn't work better ...

I heard this process : move the private keys to another wallet ... But I don't know how do because I am newbie lol until now I used my wallet only for somes transactions, no more!

So i've given some suggestions. And importing/exporting keys might cause some problems. But backup wallet won't. Wink

//And i thought he will know about shred, sorry its my fault Roll Eyes

Did you try to Tools -> "Reset Blockchain and Transactions" (not sure what its called in french)?

Your bitcoin are not lost, dont worry. If everything else fails you can still move the private keys to another wallet.

yup! Import your private keys Wink

or may be backup your wallet and as well as the private key, then reinstall the multibit client and open your wallet or import the private key which you backup.

I've face the problem on my mutidoge wallet. I'll do like as i said above Grin

~Rude Boy

THANKS FOR YOUR REPLY!!

If I import my private keys, I can uninstall multibit and reinstall without lost my btc, right ? Every information of my wallet it is in this key ? Same question for backup.

yeah! Sure any one of the option (backup or import private key) is enough. But for some reason doing both the option (backup and importing private key) is recommended. After than shred your private key file. Wink
