Can you confirm it crashes at the texture loading, even if you leave the window sitting there for say 10 seconds?
Well in both version the error message pops up, if i close this in any way, the main-window closes too. If I just leave the message open nothing happens.
Oh and in the windowed version a text appears in the upper-left, but only a "y" with two points on top of it.
I just updated my drivers from 56.?? to 61.??, but that didn't help.
