Can't select a plan on pro sites

Hello,

We are running pro sites on our website. We had a user that created an account, but did not proceed with the payment step. She is now a registered user for the network, but not associated with a site.

She is now ready to sign up and logged into her account. When she tries to sign up it says "Sorry, but it appears you are not an administrator for any sites." So we go through the process and try to sign up like a normal user, but it never gives us the option to select a plan it only shows us the "Sorry…" message (or nothing at all). It should display the boxes with the plan options, but instead it displays nothing.

We have granted in case it is needed.
