I tried installing the upgrade but it bombed out, I figured I would rename the URL so they coudn't find me as easy and that didn't work. After a few hours of thrashing around I managed to drop my sql database & destroy my guestbook. I submitted a request to support to have my site rolled back but the request was bounced because I am not the owner of the site (just the admin). I sent an email to the owner & now I am waiting for the request to be worked. Once thats done, I will be back where I started.
