Edit your userlist within CB > List Management and ensure the pagination parameters are correct. More than likely the number of users displayed per page failed to migrate so it's trying to display all your users on 1 page.

You bought CBSubs, which provides support for CBSubs only and has nothing to do with potential CB migration issues. Did you mean to purchase a Professional or Developer subscription?

Have moved your topic to general discussion as it has nothing to do with CBSubs.
