Aparatus V2 Broken after attempting to add adsense

Ok so I purchased the Aparatus V2 theme for wordpress from FearlessFlyer.com (the authors site) and I set about making my website look better. The problem is I wasn't pay attention and instead of simply putting the URL for an ad I copied the entire adsense ad. after refreshing it I got a broken image picture on my site, and when I went back to remove that text all there was was a "<script type=", which was in the text field, and next to that was "<\" (all without quotations). I then entered the adsense code a second time (what? I was testing it) without the ending </script> and the beginning "<script type=" (again without quotations).

Now, there is "<script type=\\<script type=\" in the text field and nothing under that on the admin menu for the theme (there was a list of other places to put ads), and there is nothing wrong under the theme options file. And now the theme and the wordpress toolbar when im viewing my site.

I tried removing the theme but that didn't work.
Help?

Note; I attached screenshots, hopefully they will help show what is wrong.
