Help - Error - Re-installation question/problem

[Tej]

Hey,

So I'm a long time Calibre user who has limited understanding of how Calibre actually works down to the code. My computer ran out of power while Calibre was on. It caused an error that no longer allows me to even open one of the Plugins (Generate Cover).

It says when I attempt to that a "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. 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..

I guess my question is two fold...is there some trick to completely deleting and re-installing calibre? Or am I going to need to try to figure out how to fix it with Python commands?...god I hope not...

PS. if this isn't in the right forum category let me know and I can move it...

Thanks.

We need to see the full error details. When you see it, you can press the "Show details" button to see the full error, or press the "Copy to clibpard" button to copy it and then post that.

As to where to post, each plugin has their own thread Plugins sub forum. It is best to post in that thread.

I assume since your pointing me toward the plugin forum that deleting calibre isn't likely a solution that will easily fix the problem?

No, reinstalling calibre is unlikely to change anything. And I've answered in the plugins thread.
