Changing domain makes head hurt!

I’d installed my wordpress to http://www.passinreviewonline.invisionzone.com/wordpress/…. some time ago and just today had the “.invisionzone” part pulled off by IPB, the people who are hosting my site. Anyway, I can’t get to my admin page anymore. Even when I put in the proper address for where the admin file i located it tries to go to the .invisionzone address instead of the newer, more slender one. There must be a setting somewhere I that is telling it to look for in invisionzone part. Where is it so I can change it and get back to using my blog?
