Cannot decrypt file encrypted with enQsig

[Felix E. Klee]

Now I tried a different card reader (after restarting Windows 7x64).
This time it’s a Cherry ST-2000. Previously it was a ReinerSCT
cyberJack.

With the Cherry I get a different error message! This time it’s “Invalid
value” instead of “Invalid ID”!

*What does that mean?*
