FairUse4WM Problem

I used FairUse4WM three days ago to remove the drm from 4 wmvs and it worked fine. DLed two more wmvs from the same site yesterday, played them on WMP to obtain licences but now FairUse says that the wmvs require a different private key! What gives?

I don’t see a drm key anywhere in my D+S file!

Can anyone please help me?

Thanks!

My computer seems to have solved the problem itself!
