You all talking about drmdbg that is old one.
There are few new released drmdbg that is easy to use and working perfectly.
You only need two tools to un-drm any protected .wmv or .wma :
1. drmdbg.exe (there are version 527, 621, 1111, 1113, 1201, 1204, 1207, 1211, 1212, 1213, 1214)
2. drm2wmv_e.exe
Once you have licenses for the protected .wmv or .wma in your computer, you can get SID from indivbox.key to decrypted your protected files using these
drmdbg and
drm2wmv.
Note: If you install update KB891122, it updates many of the DRM components in your system, then drmdbg will not work anymore. Use only WMP9 or WMP10 v.3646 without any Windows Media Runtime updates.
