Problem using drmdbg. Need instructions on how to use drmdbg.exe

I have downloaded drmdbg.exe v11.0.6000.7000 and have unzipped etc.When I run it I get what I expect is the standard input box but am not exactly sure what to do now. I did create an output file for DRM2 DIR box and entered the input directory into WVM DIR box . Do I enter something into the MULTI Scan box? I have tried entering the same directory as I used in the WVM DIR box, the name of the track etc but as this doesn't work I am obviously doing something wrong. So how do I proceed? I am working on audio files wma not video does this make a difference?

I haven't used code for anything in this century although I have a hazy recollection of some terms so please be explicit and keep the terminology simple.

Thanks
