Creo 7 crashing after downloading Creo 11

Hi everyone,

I recently downloaded Creo 11 on a machine with Creo 7 in order to test something. After deciding to test on my virtual machine, I uninstalled Creo 11. I now get this error in Creo 7: 

When checking the logs, the error reads: EXCEPTION_ACCESS_VIOLATION has occurred in the thread 3772. I've tried clearing cache and reinstalling. Any ideas?
