I will try those doors myself and see what happens.

I don't have issues with that neither.  When I last corresponded with her in
2016 she gave me the key generator and to have at it.  

Ok.  Just tried it and I was able to register Leviathin Reef using my Name
and my BBS name  (Ruben Figueroa and Prison Board).  Worked just fine.
