In order to be helped, admins and mods do need to know what your account name is, what URL you are using and the server. Without this information, we can only make guesses on what the problem may be. Also, this forum is to ask general hosting questions. If you have Heliohost related question, I would recommend to post in the Customer Service board. For the DNS3-DNS6 problems, I assume you are talking about the name server records? You can leave the others black, but make sure you have ns1.heliohost.org and ns2.heliohost.org filled in.
