Webmatrix 3 Stopped working

Hello,

I just downloaded Webmatrix 3 on to my Windows 7 64 bit machine -- unfortunately, I'm having problems where it crashes whenever I attempt to A) open or B) create a website. (This includes remote sites and individual files.)

I've uninstalled Webmatrix 3, IIS8, etc. etc., and reinstalled (multiple times), but it's still crashing. 

If someone can point me to the location of the log file, I'd be happy to post it!

Thanks,
Mark
