Q&A full version pushes my sidebar down!

I have just upgraded from to Q&A full version from the Q&A Lite. Q&A Lite worked perfect, now I have the full version it has too much "width" and pushes my WP sidebar all the way down so it is not visible anymore until you scroll down. You can see it here: http://yoga-health-blog.com/questions/ask/. How do I fix this problem? Please explain this to me easily as I am a newbie.

Many thanks, Michael
