Audio Error?? Movie Maker does not support these selected file types

I am having an issue with an error when trying to add the audio from the SAME saved WMM (.wlmp) video saved. It says Error Movie Maker does not support these selected files?? (Its the same file I just saved to try and upload the audio so I can edit....:-(

I tried the Microsoft Codec fix link...........NO Luck.....

I tried converting the file......But the converters don't seam compatible with wlmp files....

Any help with this error or a converter that converts wlmp files to avi ????
