Tried to 'domain map', now both URL's disfunctional

I've left this for a few weeks to see if it was just a change in nameservers or something taking too long, but that's not the case.

I added my personal domain name http://georgefourie.com to my mu blog at http://georgefourie.thatmlmbeat.com

The domain was still hosted at hostgator and after a few days of struggle I decided to point the nameservers back to Godaddy, park the domain and add it as a addon to my host, which is how I got my previous domain map attempt to work.

What's weird is I cant get my blog url to work at all so that I can remove the domain map and start over.

How can I 'reset' or remove my domain and get my blog url working again?

Thanks,

George
