Help!! I installed Creo 2.0 on my windows 8 and it will start but then quit!

I Have no idea what to do. I have installed the student edition of creo 2.0 and when I try to open any of the files in my lisencing, they will only start up for a few seconds, then quit. I have tried uninstalling and reinstalling the files, even restarting my computer. Any ideas on how to fix it?
