MobileRead Forums - View Single Post - "invalid PID checksum" when using mobidedrm, even though it IS valid.

Sorry if I am bringing up something that was answered. I looked through the posts and I believe that my mobipocket books that I bought must be content-encrypted and not necessarily tied to a particular device since I can view them on any device/computer as long as I view it with Mobireader. The problem is that I now have an Android phone and I want to be able to read it with that. It appears that Amazon has no intention of creating Mobireader for Android. Since I paid for the books I have no qualms with decrypting them. I have tried the mobidedrm and it keeps giving me the Invalid PID checksum error but I'm wondering if I need to actually use mobidedrm005 since my books aren't associated with a PID. Is there some other way to decrypt these? Thank you so much for any help!
