I'm having errors running the script. I have activestate python on XP and I'm trying to liberate the free Around the world in 80 days from fictionwise. The PID I have is from my laptop installation of mobipocket reader. Could it be problematic that it contains a $, which could be badly expanded as a variable at some point?

I could not wait and tried to run the script on both the N800 as well as my XPP-PC. Both running Python 2.5. I get the same error in both:

So it's not my system. I can say this file contains two books. But I am unsure if that really matters.
