I just bought Mountain Lion. It downloaded and I installed it and it restarted my laptop but nothing happened. When I went on the app store it was in my purchases, but had the download icon next to it. when I click on it it says:
"You have updates available for other accounts. Please sign in to the account used to purchase this to download it."
But I don't have any other accounts, and I am the only user on this laptop.
Any suggestions?
