Expired subscription

I created a test profile for a 7 day free trial. I got my notice in my email that the trial ended. I clicked on the link that directed me back to the website to upgrade my package. Only thing is, once there I wasn't allowed to do anything, I got this no permission page. I clicked on sign up, and when I did, It stated duplicate email when I try to create a new profile to upgrade. So basically, the page I'm being directed to is not an upgrade page and I can't upgrade because my email is already in use. What are my members to do once their free trial ends?
