Problem with Autodesk 3ds Max

Hello, I have a problem with Autodesk 3Ds Max 2011.
I had no problem installing it, but now after the start up and loading I’m getting an error message:
Reset Ribbon?
The main Ribbon configuration file is possibly corrupt. Reset to factory defaults?
Yes No

I’m using Windows 7, but I didn’t have any trouble with Max 2010 before so I’m not sure what could be wrong now.
Thank you for the help, I greatly appreciate it.
