I don't know from here the problem, but please give me a call then we can try and fix it. As I'm one of the moderators we can get to the clou. I checked it: You ARE member. So I think you receive all e-mails as well.
Might it be that you used several different PCs for setting up so that the current PC you are failing with has perhaps only "welcome guest" in the top instead of "welcome e-mail-adress" ? This would explain your problems.
When the problem is fixed, we can publicate it in this group.
