Hi everyone, I have the same problem as many of you but I simply cannot make it to work in any way. I want to read it on my cybook !!!

I bought a book from mobipocket (never ever anymore I'll give you my money you stupid bastards) before putting the name of my device, installing the software or anything.

I use linux, when I downloaded the file from the website Calibre said it had drm. I installed mobiread in my windows paritition and downloaded the file from inside the program, it asked me for login and password and opened the file. I then plugged the Cybook, with the mobipocket firmware, uploaded the file which opens just fine.

I then checked online for dedrm and followed the procedure. I tried using the file directly downloaded from internet, the one on windows after I had opened it, the one on the reader after I had uploaded it from the software and opened it inside the reader. I tried each one of these options with the ebook reader pid, windows pid, even mobiread under linux wine's pid (they all show on mobipocket website).

NO SUCCESS, it always give me Error: invalid PID checksum

I want to read this book on my cybook reader with its epub firmware as I have numerous epub books, I need to dedrm it and convert it.

Please guys help me, drm suck so bad it hurts
