Need URGENT help!

www.2.tonyperez.biz is the site. Go to any of the posts. The text is in the top right! You have to push enter twice when posting to make it align properly.
What I done was swap all images of another theme over to the default theme, and I swapped the CSS files around. Now its messed up! Help please.
PS - Yes, I know I shouldnt mess with the default theme, but I needed to do that as the ad wouldnt appear in the top right.

Does the page validate as w3c compliant?

The ad is screwing up everything. You would probably be better choosing a smaller ad to put in that position!

I've got rid of that forum a while ago.
