hello guys, just finished downloading SA (4.7GB). i have the following configuaration, intel p4 1.8Ghz, 256MB ram, 845GL chipset(intel extreme graphics) and have all directx 9.0c compatible graphics and sound card drivers. the problem is when i start SA, the game runs till the credits video is over (or when the copyright notice is displayed) and exits abruptly to the desktop. please help me to solve this problem, i've wasted time on downloading 4.7GB of stuff. i heard that SA runs fine on intel extreme graphics. what could be the problem?
