Registration issues

I see. I've now deleted the RegisteredVersion line in the highlighted Configuration Setting File but when I try to build I still get the same message, "User is not registered" etc. How do I actually re-register? I tried to reinstall the game via my license key in the store as afrlme suggested in the first reply to this thread and it hasen't worked (I got the, "User is not registered" message again.

After you've removed the key the menu should contain an entry "Register Editor".

It worked! Omg thank you so much all of you, y'all were super helpful.
