Jedi Knight II from Mac App Store won't start on 10.8. Suggestions?

About a week ago, I purchased Jedi Knight II from the Mac App Store despite already having a copy purchased years ago when it first became available for the Mac. Naturally, I figured that with a high percentage of people using Lion and Mountain Lion, if there were a problem with this game, it would probable not remain on the app store. I downloaded it and attempted to launch. The screen where you choose if you want to play Windowed or Full Screen popped up just fine and I chose Full Screen. I waited a while and nothing happened. I attempted to choose something from the related menues that popped up and all I got was the spinning beach ball. When I opened the "Force Quit Applications" screen, it said the app was not responding. This is what I have gotten consistantly every time I have tried it. I figured that before I go to apple to request a refund, I would ask if anyone has had this issue and if you were able to resolve it.

Thanks,
