Potwallet.com is private and not official. If you used 3rd parties the problem is at their end. Better stay with official software.
But i heard about the problem and there is a solution i think, but i do not know it.
Join the telegram chat and i think somebody will help you out.
Ahh I finally found the Telegram chat. Searching potcoin on Telegram doesn't bring up the official chat channel. Had to find it from the BCT post
I'll update how it goes, and if I can convince them to either take down their site until they can up keep again or put a huge warning banner on the site.
