How to reverse a boneheaded double forwarding domain situation?

Hey all,

Ok, not my brightest moment. I have a big fellowship application due in a few hours, and I created a domain name specifically for this application with my latest portfolio on wordpress (e.g., kevinapp.org). My intention was to forward my normal domain (kevinhome.com) to this domain, so that for a few weeks all anyone would see would be kevinapp.org. The other option would be to do forwarding w/ masking for kevinapp.org, but I wasn’t sure if sub-domains would work on this (e.g., kevinapp.org/blog).

First, I went into GoDaddy and set up forwarding w/ masking for kevinapp.org. Then, without seeing it live yet (oops, should have been patient) I went ahead into the wordpress settings and changed kevinhome.com to kevinapp.org, and hit save. Now I can’t login to wp-panel at all, and neither works!

What would be the best way to fix this situation and achieve my initial desired outcome? Thanks so much.
