In OE MP3 attachment not associated with program

When I receive an email in Outlook Express with an attachment that is an MP3 file I get an error message when I try to play the file within OE. The error message says I do not have a program associated with the file and I need to get that done in the Folder Options Control Panel.

When I go to the Folder Options Control Panel I find, as I expected, that I do have a program associated with that file type (MP3). The reason I expected to find the association is MP3 files outside of Outlook Express play just fine. In fact, if I save the attached MP3 file it will play just fine from the folder it was saved I just can't play it while it is attached to an email.

Never had this problem before but I reformatted my HD and reloaded XP Home and since then I've had this problem. Haven't found any other file types giving me any trouble.... yet.

Obviously I'm stumped....

 

No one has any idea?

I have to say that I've never had a problem that didn't get a response even if it was something like... oh, how bout, "That's impossible, it can't happen! "

In any case, if I figure it out I'll post it.
