When I attempt to start calibre, I get the splash screen and the usual messages, "Starting calibre: loading books," then "initializing user interface." After that, the message comes up, "The main calibre program has encountered a problem and needs to close."
When I follow the provided link "to see what data this error report contains," I get lots of numbers which mean nothing to me, and which I cannot copy and paste, anyway.
I tried multiple times to open calibre with the same result. I tried re-booting my computer, as well. I'm using Windows XP and calibre V2.0

Can anyone tell me what I should be doing next? Thanks!
