Open windows search, then type in and search %appdata% then click on the roaming folder and find the folder related to xqn.
Delete everything except your wallet.dat and try reloading the wallet.
I'm pretty tired, not sure if I understand the problem or not. Hope that helps.
Do you have the newest wallet version?
yes i think, all i need is the file called wallet.dat? should i delete the folders aswell or just the filles beside wallet.dat?
if i delete everything and save my wallet.dat and then install the wallet again and putt wallet.dat on the folder will i have the coins anyway?
thank you for your help!
Correct, all you need is the wallet.dat file - that contains your private keys.
1. Backup your wallet.dat to somewhere safe (usb drive or something) - just in case something goes wrong.
2. Close the quotient client.
3. Delete everything in the quotient directory (found as above by going to %appdata% -> roaming) EXCEPT your wallet.dat file.
4. Start quotient again.
5. Thats it. You do not need to replace the wallet.dat file as you left it there to start with.
We'll said, my explanation was pretty bad.
