Problems after downgrading to version 3 again

Hi, I have an urgent question. Since the upgrade to version 4.02 was making problems, I went back to the older version. But now I have the problem that when clicking on the "my courses" button in the dropdown-menu on the right upper corner, I just see a very small picture with the error massage: "Create a Member Profile layout in WP admin - Member Profiles". Keep in mind that I have deactivated and even deleted the mentioned plugin. Before the usae of the new version the site worked pretty good. Can you please help me with this problem? It might even be faster if you would log on and do the job for yourself. I will post the admin-logindetails below: Thanks a lot.
