Thanks, I hadn't changed in personal.ini yet (I mean, the changes I had were all from when I first installed the plugin, the user/psw and a couple more things), I decided to upgrade first, in case what you all were discussing wasn't possible with my not up-to-date version.
Updating calibre seems to have fixed it, I tried the same procedure on the same story and no error this time, I also Downloaded a new story and it was ok ^_^
Now I have to try and understand the rest
