I did have a play with the trial version, i didnt need the full version as i coverted all my protected files and loaded them into WMP before i found this tool.
It does require to have itunes running in order to work.
It seems to work and copies all the references into WMP, but does not copy across the Album titles or the track sequence, which means you have to fiddle a bit in WMP before you can use album art fixer.
But now i have got all the music into Media Centre and they seem to play properly.
