Hi I've read a lot of the other threads and tried uninstalling and reinstalling the game and made sure my directx was up to date. When I start up the game and use the small window to "launch game" it takes quite a while for anything to happen, but the game does eventually start up. Then I can play for a while but inevitably I will go through a spot that changes the scene (I can have done it several times already) and the screen goes black. You can still hear the sound, but then my monitor will blink off and say 'no signal', but then come back on a few seconds later. The screen also goes from black to white (still hearing sound, just the background sound) and the only way to get the program turned off is to press the shortcut on the keyboard to the start menu. This brings up the bottom task bar and then you have to right-click the game bar and hit 'close'. Then it finally brings up a 'end program' dialog and you can end the program. Sometimes their is an icon in the bottom taskbar and that says "display driver igfx stopped responding and has successfully recovered". But even if you just leave the game when it stops responding, nothing happens and you have to kill it using the method I described.
This sucks, I already played the other chapters on my friend's computer so I haven't tried any of the others on my own computer yet--but if this is what it is like, meh! When it crashes, I lose anything I've done that wasn't saved, and then have to wait a long time to close the program, wait for my computer to recover and then have the super-long start time again--and then it might crash again 5 minutes later.
My computer plays all kinds of other games, without any problems and I'm running Vista. Thanks in advance for any help!
