Well, I suck.
I was trying to move my wordpress.org blog from robbschuneman.com to my newly purchased domain at http://www.domesticllama.com (purchased through wordpress.com) - following the instructions from this help file: http://codex.wordpress.org/Changing_The_Site_URL
The end result was a crashed old site (robbschuneman.com) and a still default new site (www.domesticllama.com) - and now I'm unable to get back to the admin page.
I am a moron. Please help me. I'll be glad to provide whatever information I can and would be incredibly, overwhelmingly, grateful.
Thank you!
