I figured out that if I window the program I can use C-A-D to get to the Task Manager and close SRO. But now when starting the program I get a series of errors:
dxdiag gives me errors also when doing 3D tests (color is wacky because I made it a lower quality bmp to reduce file size, my screen color is fine):
EDIT: All errors remain after logging off and on, all errors disappear after restarting completely. I don't expect someone here to know how to diagnose this, but does anyone have a good idea to whom I should send this information? It's good to have something, at least it's not a faceless problem any more.
