Cannot login to admin after changing domain

[sohot]

I had installed soholaunchpro 4.7 on a subdomain while I edited the web site, and have now moved it to the main domain name.

I am now unable to login to the admin area because it keeps trying to default to the sub domain.

I presume there is a config file somewhere that I can edit to change this. Where is this located and what is it called?

If you find the config file let me know I did the same thing with the same problem.
