I've been running windows 7 for a while now, and had no issues with Halo 2 on my machine. I had uninstalled H2 simply because i wasn't using it at the time (school/distractions). Now, i have gone back to re-install H2, and it is giving an appcrash error at startup.

I have tried all manner of troubleshooting i know of (including the ones listed in the stickies. Just wondering if anyone else has encountered this issue, and if so, did you manage to get it working?
