Oh, so it's a information gathering tool. It, strangely however, does seem to be what is causing the probs, it seems the act of it running is what shuts down the game, no matter what game it may be, admittedly i have only had the chance to test it on 3 games at present. All the games are perfectly legal. At first i thought it might be that fact that windows was not up-to-date, so i updated to sp3, but it made no difference. Drivers are up-to-date aswell.
