MacBook late 2009, 8 GB RAM, 240 GB SSD, was running Lion just fine. This is an App Store purchase. During the Mountain Lion install it went to sleep and upon waking said it couldn't be installed on this computer. The only option it gave me when choosing a startup disk was OS X 10.8 Server (!) so I selected that and now I'm stuck on Cupertino time (I live in CT) and my admin password no longer works. In fact it downgraded my user account to a Standard account. I have never had any other users on this machine. How can I restore my account to an admin account? PS this is my 1st attempt to upgrade to Mountain Lion on this machine. All attempts to upgrade my iMac i7 from 2010 failed. I've tried downloading the ML installer 6 times with the same result. It reports that OS X 10.8 can't be installed on this computer after the install screen.
