I got this game bundled with a Creative Audigy 2 ZS board. At the same time I replaced the Gforce 2 withan ATI Radeon 9550. I installed it (plain old Splinter Cell) and it will not even start. The little Splinter Cel logo comes up on the desktop, stays there for a minute or so then I get an error message that says "SplinterCell.exe has encountered a problem and needs to close." and wants to send an error message to microsoft. I have XP with sp2 on a Pentium 3 900mhz. It looks like my processor is fast enough, but just barely. Any ideas?
