OS X Mountain Lion is temporarily unavailable.
I have uninstalled all user files in an effort to start over on my system. I am able to make it as far as the sign in screen in Install OS X and then while waiting for the Mac App store to download OS X Mountain Lion I receive the following message, "This item is temporarily unavailable. Try again later" How do I proceed with reinstalling my OS when it is temporarily unavailable? I am now unable to use my MacBook Pro at all as every time I turn it on it will go directly to the OS X disc utility.
MacBook Pro, OS X Mountain Lion (10.8.1)
