Pro sites login redirect after creating site

Hi, I am using Pro-sites for site creation, allowing a free blog option. In the test phase and finding when i create a new free blog, get the activation email, select that and attempt to login, i get immediately pushed to the upgrade page, rather than the dashboard of the new site, or a get started page. I don't see in pro sites where to change this. Can you tell me where this is set?

Thanks, Susan
