WMP 11 Immediate Crash (along with other programs)

I wasn't sure where to post this, but since it affects WMP 11 as well, I posted it in here.

The second I try to load up WMP11, I get the "Windows Media Player has stopped working" message, and then it crashes. The same thing happens with Zune and Windows Sync Center (which is something I've never used).
