Mimbo screws javascript of quizzin plugin and phpfreechat

I have met with Mimbo which is very smart for me but i’m having some bad experiences with it although i’ve customized it for my needs.

The problem is Mimbo should show each question and after choosing an option, the next question will be shown. But it doesn’t work like this. it seems Mimbo cannot load necessary .JS and .CSS files of the plug-in. What might be the problem?

Thanks in advance
