FairUse Commander *System could not find the spicified file*

 

Hey guys, I just downloaded FairUse Commander from mediafire. I open it, have it search for my zune drm protected songs and it finds them. I highlight all the files and click the big green "Remove DRM!" with batching enabled and "remove no drm prefix" enabled. An error pops up that says "System could not find the specified file". I've tried doing 1 song at a time but the same thing pops up every time. Please help!
