Does anyone here know anything about Windows Movie Maker?

Someone sent me a small video file that I *really* need to view, but they sent it in .MSWMM format and Windows Movie Maker won’t run on my PC. 

It won’t convert to anything I’ve got, can’t be viewed in anything I’ve got. 

Does anyone know of a WMM viewer, or any conversion software I might use to view the file??

Thankies....  ------------------------------------------------------------------------------------------------------------------------ physiotherapy perth
