3DS Max 2010 crashes when I try to access the menu bar

I am able to open the application, create and manipulate objects in my scene. The problem is whenever I need to access items from the actual menu bar (Edit Tools Group Views ... )I get a dialog box that says:

Application Error

An error has occurred and the application will now close. No scene changes have occurred since your last save.

I click okay and it automatically closes the program.

I am able to save work by clicking Control-S. But there are other items I need to access from these menus as well.

So, it only affects items in that menu bar when I click.

I am running Service Pack 1.

Any help or ideas would be greatly appreciated.
