BumpIn Chat Widget Nextgen Gallery Problem

I just installed the BumpIn chat plug-in. It works fine on one of my websites but on another, when I install it, my Nextgen galleries stop working.

I’m using the Autumn Forrest theme and figure it is a javascript problem. Wondering if anyone else has experienced this and has a solution.

I’ve removed it from my site for now as the gallery is more important to me than the plugin. In the meantime, I’ll keep trying to figure it out.

Thanks,
Wendy
