Fairuse4WM error: file does not appear to be licensed to you. How to set up WMP?

Hello, long time reader, first time poster.
ok well i have IBX 11.0.5497.6285 and i have bought a movie (legally) and am trying to remove DRM, however i keep getting the error that the file does not appear to be licensed to me, i can still play the movie, but why can't I remove drm?

I have tried to play the movie and pause it while i use FairuseWM, and that doesn't work, now i was looking around in these forums, and came across the FairuseWM Errors thread, and that says to set your WMP to "ALWAYS PROMPT ME FOR MY LICENSES". How do you find that setting? I found "PROMPT ME TO BACKUP MY LICENSES" but that is a different setting, do you guys think you could help? thanks a lot in advance!
