fsagame.exe is the name of the game's executable, so all that error is telling you is that the game stopped working.
Make sure your antivirus is not blocking the game. You may have to add "fsagame.exe" to the "allowed" list of your antivirus. Also if the game is trying to contact Steam, it may be being blocked by a firewall if you're using one.
The most important part of the specs for playing current games is the video card. Make sure your video card meets the system requirements. According to Steam, it needs
DirectX® 9 compatible Graphics card with at least 128 MB RAM
which is fairly low end. So unless you have Intel graphics or some other onboard card without discrete video memory, the video card is probably not the problem.
I'm guessing either it didn't install or activate properly or it's being blocked by an antivirus.
