I had a similar problem today in that the audio file I just down-loaded will not launch. Just last week everything worked fine. When I try to play the audio file from my mydocuments folder, it opens an error dialog box saying that the file I am trying to open has an .mp3 filename and am I sure I want to open it. When I indicate "yes", it opens an internet download sequence, which subsequently activates a virus scan. Nothing ever happens. But all my previously downloaded .mp3 files work just fine. Ever seen this before? What's wrong?
