Polispay debit card had a little setback. Just a friendly information for you guys. I guess they will find a solution for this, so i wish you all the best to get listed on their plattform.

finally.
it seems like I was having problems with some corrupted file on my database.

could find out by checking the debug.log

here's what I did:
- backup my wallet.dat
- delete all files on %appdata% besides the backup and some other things like .conf and debug
- start wallet
- close wallet
-restore snapshot

now it's back working with no problems!
