Invalid PID with mobidedrm

Wallcraft,

I'm having the same problem as Haidon and I've carefully checked and rechecked my PID. I took your suggestion and entered the PID provided by Igor. Got the same error message about an "invalid PID checksum." Any other suggestions what might be going on?

If this works, most likely you have misread a 1 as I or a zero 0 as a O.

MobiPocket does not say how long a PID is (even though it is obvious by inspection), but it does say: incorrect PID message on web site: Here "Incorrect PID" is exactly the same as "Error: invalid PID checksum" (since that is what the checksum is for).

If none of this works, Igor kindly provided us with the PID of someones Kindle to test kindlefix.py. So try V176CXM*FZ as the PID. It will fail because this isn't a PID authorized for your ebook, but the point is this PID has a valid checksum and so it should fail with a different error message (Error: no key found. maybe the PID is incorrect).
