What did you rename the file to? I suggest rename it to "name.wmv".  Do you
have a program that opens .wmv files? (Active-Movie or similar, late
version). It probably won't open in anything earlier than Win ME, according
to my list. You could try renaming it with a .avi extension and see what
happens.

Are you certain it's not a virus? As you probably know, opening any email
attachment (and this is obviously a strange one to you) is fraught with
danger. Even if it appears to come from a known source. That's how they spread.
