Fairuse4wmCommander - black box

Hello Everyone;

Came back to edit this posting.

New slant on this: Where does Fairuse store the keys when they are extracted - that is what I need to find out?

Been using Fairuse4wmCommander for awhile. It works great.

But recently had to reset my drm file and re-indivit myself a new key.

Now new files will play on WMv10 player but not convert, keys not found.

I believe I now need to empty or delete that black box keys folder/file. Am I right about this? Saw it once, forgot where it is?

Can you help me find the black box keys?

Long time visitor, First time posting.

Thank you so very much,
