First of all was Lua error when I hit mission tab.

And then everything messed up:



(the same at D13 actually)

And when I logged out game stuck, so I ctrl+aLt+del it.

wow, nice work, that's the kind of crap they expect from me usually.

on a serious note, id hazard a guess that your are having some kind of video card issues, might be time to hit it with the air compressor and clean it out a bit.
