Fatal Error PiCoin can't continue safely
Very useful message... thank you for clearly identifying the problem and the circumstances under which it occurred.
If you're running Linux, I have no clue what your problem is, but I bet that if you muster the energy to be a bit more descriptive than "Fatal Error PiCoin can't continue safely", somebody might be able to help you.
If you're running Windows, it's normal to get an error the first time you run the wallet. Just run it again.
If you're on windows, will that happen on any qt wallet you'd try to run the first time?
