Try this... close your wallet. Now take out your wallet.dat from the ECCoin folder and put it on a save place (desktop). Now start the wallet and see if it works normally. If it does, close the wallet and go to the ECCoin folder again, there is a new wallet.dat....throw it in the wastebin and paste the wallet.dat that you saved on your desktop in the ECCoin folder again. Start your wallet and see if it the problem is still there.
...thanks mdtspain... but i already tried this.
the fresh wallet was synced without problems.
In the meanwhile I'll try to find out if I have some older wallet.dat backup that works.
I'm having the same problems, with my backed up wallet.dat.
The new wallet just won't accept it..xD
But i'm on a windows 7 x64 PC.
Trying some things but looking forward to some suggestions aswell. (=
