Using Movie Maker from the Windows Essential 2012 suite.

When you mouse over the bar, there is a dialog that says double click to fix.  Doing that brings up the following dialog:

It says that the file might be corrupted but I can execute it from Windows Explorer and it plays just fine.  I would think that the necessary codecs would already be installed that Movie Maker would need. 

The only thing that I could be wrong is that the music was downloaded under a music subscription.  Can those music files be used or do you have to fully purchase the song?  Other than this what else can I try?
