Creating a new web site when already having a website

Question

I have an Office Live web site and I just purchased another domain name to add another web site.  The problem is when I try to go to the Page Manager for the new web site it takes me to the old web site page manager.   I can't seem to find a way to get to the page manager to create the new site.   Also if I type in the domain name of the new page in the URL bar it takes me to the old web site.   

I'm guessing that I should have created this new site under the use of a different e-mail address, which I have since done that, but I still can't seem to find a way to get to the page manager for the new site and start creating my pages.
