FairUse4WM does not work for me (Error: No keys loaded). Can anyone help?

[bond007]

I have purchased wmv restricted files that required license, which I entered and they started running fine. However, when I tried to UnDRM them using the FairUse4WM program, I did not have much luck. The steps I followed are:

1. I Installed FairUse4WM 1.3 without any problems.
2. I opened FairUse4WM and clicked the “Recover Key” button (It says 0 Keys loaded”
3. I got the DrmClien.DLL has version 9.0. etc message, and when I pressed okay it went back to the first dialog box which says 0 keys loaded, and the only the Cancel button was still enabled (Exactlythe same window as in step 2).

As you can tell I am using WM 9, which should be okay. Moreover, my computer is running under Windows XP.

Can anyone help, or give me some guidance in this regard?
