mobidedrm.py error: Invalid PID Checksum

[celtie]

I've been using MobiDeDRM.py to remove the DRMs from my .prc ebooks I got for my Cybook Gen3, but every time I try it it says invalid PID checksum. I've tried with 'PID' and just PID. I'm also sure I have the right PID because it's the one I use to buy ebooks. I need help please.

When I try to dedrm ebooks, I get the message: Error Invalid PID Checksum.
What am I doing wrong?

Double check every character that can be confusing: 0 (zero) and O, 1 and I, etc.

If you have special symbols like "$" in your PID, then use "\$" instead of "$" (escape special symbols).

And try to put PID into quotes ('PID' and "PID").

Your PC PID is a 10 digit, drop the last 2 symbols of your PID and try to use it in single quotes (1234567$90 -> '1234567$' ).

I have the same problem. Solve: change PID into Upper Case
Ex: Wrong PID: abcde2f$g5
Right PID: ABCDE2F$G5
good luck!
