[How Do I?] need to fix this problem

[Hawkhunter]

The first time I was playing the game it worked fine till I got my rogame.exe error. So when I fixed that, when I treid to get back into the game. I got all the way to the entry screen..but couldn't move no further. Because all the buttons, from single-player through mp, settings and even exit buttons. I could not click on them. They light up, but they would not be clicked. I think this is an error, but I tried to re-install the game..and still nothing. Can anyone tell me how to fix this problem...
