Hello there,
I had the issue that the game client closes automaticly a few seconds after you click the play bitton of the laucher. The is saw the upper workaround from wiewio to rename/delete control_modes.pyc.
The lead the client to not crashing anymore, but now it shows only a black screen and stay so. I waited about 15 mins and nothing happened.
When I remove everything from the 0.9.4 directory everything is working flawless, but w/o the mods of course.
