Help!! After I installed the new OS X update onto my Mac, my App Store application does not open and has an error that says to check with the developer App Store works with this version of OS X.  I also tells me to reinstall the application, which I don't know how to do.  My Mail application will not open either.

MacBook Pro, OS X Mountain Lion (10.8.2)
