Not sure if this has been covered or not, but I get this error message after I click Login. Help?

I know that Ubuntu and Linux don't use DiectX, so that possibility is ruled out. My video card works, I played Regnum on this comp when I had Vista. That means my problem is #2. Any ideas what drivers I should get? Thanks. If you need any additional info feel free to ask.
