Hmm... Don't really see anything there that I know for a fact would cause the problem, though I've had some graphical problems after running any Adobe-line programs (they seem to use way too much RAM and leave traces behind after closing). All I can suggest is make sure the programs are completely shut down before you play again, and always close all brograms running in the background that you don't absolutely need to play the game. Sorry I can't help more.
