As a quick check, can you make a new user account, give yourself full privileges and log in. What does the About this Mac say?
About this Mac says current version on new admin, and logging into Mac App Store lists Mountain Lion button as "Download" too. I'm going to try to restore the system and take over my stuff manually.
UPDATE: I wiped the hard drive and did a full restore and the Mac App Store still lists Mountain Lion with a clickable "Download" button, as opposed to listing it with the greyed-out "Installed" button, as it should. This seems to be a bug on Apple's part. I'm going to now use migration assistant to bring back my Mac to the way it was. I hope Apple sorts this BUG out. And it is a bug, so don't any of you cult members question me on this, or dare suggest it is my fault. Moving on.
