If you add a <br/> tag after the userbar in the Post Bit Templates > postbit_classic template, that should fix the first problem.
For the second problem, are you certain you've uploaded the js files supplied with the plugin? If you're certain, check Ungrouped Templates > headerinclude to see if the JavaScript is included in the header.
If you still cannot get it to work, I have no problem being a temporary admin and fixing it.
