drmdbg and freeme2 only works for some Unbox files

[jeri]

I've successfully unlocked one series of videos from Amazon Unbox but am having problems with 2 others I've tried. The files play fine in Unbox or in WMP when running dmdbg. drmdbg finds the SID with no problem. When I run freeme2 it either goes out and never comes back or crashes. Anywhere from 4 to a few hundred kb are written but the file is corrupt and won't play in WMP

Details:

IndivBox.key v11.0.6000.7000
WMP 10.00.00.3802
XP SP3

Reinstalling Windows isn't really an option unless I set up a new partition and I don't look forward to that.

Thanks for any help and/or advice.
