I've just finished editing a series of short movies, and saved each of them under the "Save As" option in Moviemaker. They are saved as moviemaker files.

When I try to Add them to a new project to put them together, I get a message saying "Moviemaker doesn't support the selected file type". But this is the filetype its just used to save the file in the first place! There are no options under Save As to save as a different type of file.

Please help as I need to get this project finished!

Many thanks.
