Pro/Engineering shuts down immediately after startup.

I'm running Pro/Engineering 5.0 Student Edition on Windows 7 ultimate 64bit. with intel HD graphics 3000. The processor is a intel core i7 2.70GHz. I'm running this in bootcamp on a macbook pro early 2011. The last time I ran proe was 3 months ago and it ran fine. I recently moved and have a new isp. The other day I launched the program and it starts up but then immediately shuts down? Has anybody else experianced this problem...any solutions?

Thanks,

Jeff
