subscribe2 theme conflict?

I have been using subscribe2 for a long time. I have a link to it in my sidebar. I just changed my theme. the link is still in the sidebar but when I click on it, you get a screwed up page with the subscribe form at the very bottom…Help!!! I am wondering if it has to do with it being a 3 column theme now and not a 2 column one.

also, Is there a new plugin now that people are liking that does the saem thing?
