I was hoping to use the Q&A plugin

I was hoping to use the Q&A plugin on a members/documentation site I'm putting together, but it is totally trashing my theme (Karma)

http://docs.globaleyeimages.com/questions/ask/

Wondering if anyone has any ideas on how this might be fixed? The theme is non-negotiable but I'd really like to use Q&A.

Any ideas how I might work around this?

Thanks

Matt
