Changed domain name breaks WordPress

Hi There

I recently bought a domain name and hosting package, successfully uploaded WordPress, and started blogging.

I then realised the domain name was incorrect and purchased the one I wanted. I changed the primary domain associated with my hosting account and redirected the domain to my hosts name servers. My hosting account is now linked to the new domain.

All of the WordPress set up still refers to the original domain so no images display because the path is wrong. More importantly, I cannot log into WordPress anymore.

Is there a way round this? I know that on one of WordPress’ admin screen it refers to the assocaited domain …but I can’t access this because I can’t log in.

OR should I just re-load everything and start again? I have all the original posts stored locally.

Cheers

Si
