This is the second time I'm experiencing this problem.
Created a file (say Rev 1) in Project 2007 at work and took it home and updated it using Project 2010. When I finished updating using Project 2010, I saved the file in Project 2007 format. Came to work the next day, opened the file using Project 2007 and did a "Save As" so that I have another revision of the file (Rev 2).
After updating Rev 2 in Project 2007 I closed it but when I came to work the next day I couldn't open Rev 2 file again either in Project 2007 or 2010. This has happened to me with 2 different files.
The error message I get is
An unexpected error occured during command execution.
