My app store will not open for me. I'm trying to upgrade my OS.
Everytime I try and open my app store, I receive a popup that says "App Store Quit Unexpectedly" and that it will be sent to Apple immediately.
I can't figure out how I'm going to upgrade my OS if I can't open up the app store, and haven't been able to for several days.
Any ideas?
MacBook Pro, Mac OS X (10.6.8)
