PDurrant - sorry if this is a terribly newbie question ... but where would I find a Mobipocket ID, if I had a mobipocket file I wished to run the script on, on my mac?

I should add that when I first click on the script you put up there, it asks me to navigate to a folder with a .prc file in it: I do that, select a file and up pops a window with some letters and numbers I assume are the associated mobipocket id. The mobidedrm v3 doesn't work at all, but the v2 does; however, the resultant file is zero k in size, so something's not quite right (I did rename the file to mobidedrm.py precisely inside the resources folder, yes).

I have MacPython 2.5 on my mac, which is a ppc. I note now I'm having similar problems to Seawolf - I recognised the

'./MobiDeDRM.py:49: FutureWarning: hex/oct constants > sys.maxint will return positive values in Python 2.4 and up
crc ='

bit from the error message I keep getting when I run the decoder.
