Hi,

My computer ran out of power while Calibre was on. It caused an error that no longer allows me to even open Generate Cover.

Every time I try, I get this error: "ZeroDivisionError:float division by zero" error.

Long story short. I tried deleting and re-installing the plug-in. I tried deleting and re-installing Calibre. I tried a few of the basic de-bug commands. (I'm not entirely sure how accurately I put those in). Even tried to wipe out all traces of the software with a few simple tricks. Stopped short of digging through the registry bc I dont have enough knowledge not to screw something up...

Any guesses on how to fix this problem? I heavily rely on this plugin. It would be a sad day if I no longer had access to it.

Here is the full code for the error:

Thanks.
