If I may give some tips, sounds like something is crashing your game at start up. Could be a new program or something running now that was not before. I have seen this issue many times, and should be an easy fix. If you just want to go ahead and submit a ticket, a GM can help you out of this problem.
That sounds like a video driver that is bad forcing the game to exit. Usually happens if using a set of modded drivers or even beta versions of drivers. What kind of video card are you using?
Updated DX? If installed and you tried to use a custom dx9 dll to run the game that could cause the issue as well.
