When I joined an UK exp. server, the game crashed and a window popped up saying:
"Cannot open file
Edit: This is what I discovered:
When I create the tmp -folder, the game deletes it and crashes and gives the message when I join an UK or DE server. But when I join a GD server, it doesn't crash, but deletes the tmp -folder after logging out of the GD server.
This is really annoying!
