FairUse4WM: UNABLE TO DECRYPT: Windows Error 80030002 while finding KID in V9 store

[techineer]

Is there a file anywhere that describes how to use the program?

I see references to an 'Extract keys' function, but the program window I get has no menu and no options other than to drag files into the box. How do I engage the 'Extract keys' function? (Or is that the only function?)

Using the test demo files: I've tried converting several demo files from ezdrm.com without success. Here's the result from one:

\\...\snowboard_300.wmv UNABLE TO DECRYPT: Windows Error 80030002 while finding KID in V9 store.

Is this one of the correct files? Should the program be able to extract the keys from the demo files for which we don't have the licenses? Attempting to acquire the licenses to play the demo files seems to require that you purchase their DRM encoder program.....

I'm using Win2K with WMP 9...
