one of your inputs probably invalid
In this case a rescan can help.
Thank you! Im stressing out over this so I have probably lost some iq points over here.
When all else fails you can always export all private keys and import them somewhere else, but Bitcoin Core should be able to do this on it's own.
Also I now see some older transactions which I was certain I had abandoned, their status has changed to : "conflicted with a transaction with 311 confirmations".
I'm pretty sure your wallet is messed up.
If I may suggest, backup your wallet for safety reasons then do rescan
Close Bitcoin Core, start it from a console with flag -rescan. Or to be sure, you could use -zapwallettxes to also get rid of any unconfirmed transactions you may have.
Thank you again! (I couldnt respond to your pm because I can only send 1 per hour). Yes 1Nord.. is the adress I used a lot back in the days. It is a very old wallet from 2011, and haven't used it after 2013 until 3 days ago.
I've never had such an old wallet by myself, but I often read people have problems when they use an old wallet on a new client. I hope you have original ("untouched") backups, in case you need them.
BTW If I check all the addresses on blockchain,info and compare it to the balance with the wallet, there is a rather big difference. Perhaps this info helps too
I'm currently re-scanning by adding the -rescan tag to the qt shortcut, but it has been on 1% for a while.
Although blockchain.info has it's problems, I trust the confirmed transactions they show are correct.
A full rescan from my hdd takes a couple of hours.
Do you think the btc is likely to be gone and unusable??
If you spent them in 2013, they're gone now.
