I am testing the encryption via ESM and ran into an issue trying to decrypt a thumb drive using the ZENworks File Decryption Utility, but I get an error message stating:

STLFS Error: Key not found [0x80040500]

I have formatted the drive a couple times and tried it again, but it did not work. I can't find anything on Novell's website relating to this file or error message. I have tried both versions of the tool (3.5.082 and 3.5.117) but both had this issue?
