I've tried a few methods on the support site but have been unsuccessful in getting my game to launch. I am able to enter my information, patch, but once I hit the "Play" button, the client does not come up.

I'm opening the game through Steam. System is Windows 7 Enterprise, the Steam client is running as admin.

I was able to access the game and create a character on a different computer, but can't seem to get the game to launch on this particular system. Any advice?
