MovieMaker 2.6 issues

[SamanthaJane]

We have a selection of XP and Windows 7 machines.

 

They all have Movie Maker 2.6 installed.

 

Two students have made movies on the Windows 7 PCs. They are saved as MSWMM files.

 

When trying to open on Windows 7 I get error from Windows Movie Maker 'Unspecified error'

 

When trying to open on Windows XP I get error from Windows Movie Maker 'Windows Movie Maker cannot open this File'

 

When I try to open on Windows 7 with the latest Movie Maker installed (I think 6?) - it tells me that it is incompatible - although I was lead to believe that movie maker was forwards compatible?

 

Are they just corrupt files do you think? It just seems too much of a coincidence that the only 2 students to create the file on Windows 7 are the two who cannot open now.
