Ok so here's the deal, I have bought a game from Steam created by ubisoft. This game that I purchased happens to be Splinter Cell, and for some strange reason it will not run on my computer, I have contacted Ubisoft with this problem and they said they didnt have any information for Vista so they told me to go to the forums and that is why I am here. When I go press the Icon everything is fine, then User Account control pops up (doesnt happen with any other game)then it goes indirectly into a little rectangle on my screen, I can hear no sound. I go to click on ethier multi or single player and it will say (Splinter Cell4exe. has stopped working)<-- for single player SDCA_Online.exe has stopped working. So I am pretty frusterated at this point could somebody please help me?
