What I have done so far-

I've downloaded and run mobidedrm (0.5) with the PC's PID (god knows what I am supposed to use!) and I get "Invalid encryption: type 1".

I also can't seem to get modedrm (using _plugin.py in zip file) into Calibre: It says "No valid plugin found". I've checked and re-checked the file and it looks ok to me.

Finally, in frustration, I seek expert help!
Encryption type 1 is an earlier (pre-2003 at least) form of encryption than is used for current mobipocket and kindle ebooks.

I don't know of any tool that will decrypt them.

Is there any chance of re-downloading them? New downloads might have newer encryption.
