Help! Plugin has caused front page to distort..

I installed the forumpress plugin and now my ‘older posts’ section on my front page has totally distorted. All of the meta info is either gone, too large or in the wrong place. ONLY on the older posts section. I know it’s the plugin because when I deactivate it, everything returns to normal.

Any ideas on how to resolve the conflict? I have the forum installed on a page that is not yet visible as I am launching the new feature tomorrow (or not, at this rate!) and I don’t want people logging on to it before then.
My theme is a customised Wootheme called ‘Spectrum’.
Please help, any help! Thanks so much!
