Where is my second Domain

I installed the Multi-Domains plugin, and successfully activated my second domain, however it does not appear in under "My Sites" in the Master Admin panel. Also, when I type in websiteB.com, it redirects to websiteA.com. When I try to create a new site, it only allows me to create subdomains. I was able to create sub.websiteB.com, which appears in my menu now, but I am still unable to create a unique page for websiteB.com.

How do I rectify this?

Thank you
