PZ in x64 mode doesn't work for me even though I'm using 64 bit. I'm betting it has something to do with desura because I could run previous PZ versions fine(when it wasn't on desura). I'll try in 32 bit though. When I try to play in x64 bit in desura, I create a character, and then it just blackscreens when it's loading the map. Edit: Doesn't work in x32 mode either. And my computer is state of the art, no problems at all with other games.
