In regards to deFE22001.1.0c.exe (http://sourceforge.net/projects/defe22001/files/):

I ran version C of this app and it was finding less than 10% of affected files.
I downloaded version B, and it finds the MAMBA/WAMBA keys but immediately stops and says Completed but with 0 files decrypted. Before it found many thousands of files but most of the photos were corrupted. I stopped running it so I could try version B. Both version B and C stop immediately now.

I renamed the first recover folder and there is over 100G free on the hard drive. The *.fcd files have not been modified as the original "Last Modified" date still shows on all of them.

Any ideas? Please help.
