I received the same message after upgrading to 2011 last year. Several of the technical folks on the boards offered many hours of help and troubleshooting, but we never really figured out what was up. The last thing I did was create a new user on the computer giving me issues (2011 was working great on my laptop) and installed it under that user. It worked. I had to switch to that user each time I wanted to use that computer to work in FTM, but that was acceptable to be able to get FTM to open my files.
I installed 2012 on that desktop under my usual user and have had no problems this go around.
Best of luck to you!
