I got bit by the update also.. DRMDBG and freeme2 no longer work.. I get the memory and write errors every time.
Windows said I had to update or I couldn't access the media I wanted.
Went from Versions:
11.0.6000.7000
To
11.0.6000.6324
Backwards unless they're counting in reverse.. It placed a file named Indiv02.key in my DRM folder which is version 11.0.6000.6324 and 1151 kb...
I renamed the DRM folder and went to the Microsoft site to re-individualize my PC again and the Indiv01.key it created is version 11.0.6000.6324 as well.
Original Indiv01.key was 832kb the new one is 1151kb.
