Error Message "Could not load file or assembly, 'VSlangProj, Version 7.0.3300.0 ...

I have copied a VS.Net 2005 C# Solution from a windows 2000 machine, to an XP machine, and worked on it on the XP machine.  When I tried to work on the project when it was copied back to the 2000 machine, I got the error message shown above when I tried to open any Form in the Solution.

    It's ok after all, the problem was that Visual Studio crashed and trashed a directory structure.  After a scan disk, everything was working again.
