Lost visual appearance of product on my site…

I love this plugin and it worked for me for my testing purposes when I installed it. However, when I went back the next day to work with it again, it’s appearance is a mess on my pages. You can see what I mean at this page: filo4you.com/community/ – 
The only thing I can remember doing prior to this happening was the removal of a user registration plug-in that I saw was not going to work.
Any help trying to troubleshoot this would be great. We really want to use this plugin… Thanks!
