[Plugin: ImageShack Offloader] “Warning: Division by zero” – incompatibility with ComicPress?

When viewing the dashboard I am greeted by the following error:

I’m using a system for WordPress named ComicPress which aids in publishing web-comics. It looks like ImageShack Offloader has incompatibilities with ComicPress as it’s not re-hosted any of my comics. I just wondered what your advice was? I really would like to use this, as I have a pretty limited amount of bandwidth and people have hotlinked the comics on a few occasions now.

Thanks

PS I forgot to say that I’m using WordPress version 2.9.2
