Have received the same rejection due to lack of visa information. I had the same problem as others in trying to upload 2 photos so just did the passport info page.
Have now re-registered with a new email and by dragging and dropping in both photo's at the same time. The photo upload worked but the registration was rejected as the combination of name and passport had already been used.
So have now removed a letter from my name and registered successfully. Will now wait for an email telling me my name is incorrect!
