installing on sub domain and screwed it up

Hi

I installed wp on a sub domain and made some customizations to the theme. The client them wanted the same look on his domain. So i installed wp on his main domain name.

iblob.kuhnglobaltalent.com

kuhnglobaltalent.com

then i copied from the sub domain: the wp admin, wp comment, wp includes folders to the main domain, overwriting the original install files.

Here’s my problems: I cannot access the kuhnglobaltalent.com admin page it bounces over to the iblog.kuhnglobaltalent.com admin
actually all the pages on the domain link to the sub domain

I would appreciate any tips or help the anyone could provide as this is the first time i have treid to install wp this way
