SE5 demo cant play it

[CaptainAL]

I'm having a problem too, but it is probably something stupid. I just downloaded it and am getting an access violation on start up. There are two errors: "EAccessViolation ... address 004788D3 at module "se5.exe"; and "... at address 00405928". My system meets all requirements but I am not very PC literate and I am not sure if my PC video card has 3D acceleration. It is a 64MB GeForced MX Graphics card. Anyone fimiliar or know where I could look it up? I also did not download the DirectX driver because I know I downloaded it before. If that's it, do I need to put the driver in one of the seV demo files? (hope I don't have to download the wgole program again)
