Currently stuck where when I have my old account (Daht) send me a confirmation email, it never arrives, never in spam (any of the 3 layers of filters)... this account got the validation email fine going to the same domain that forwards to my private email.

Been stuck out a few days now, keep doing 'contact us' and retrying periodically.. anyone else deal with this, or have an alternate method to contact support?

Well, Daht's unfortunate.

I actually have no idea, ard had the same problem though, so maybe he will be able to help.

Ohai. In case you haven't seen it yet (though it sounds like you tried my steps already):

So you already asked tech support (Asmodee side) for help? Did you get a response? They had to manually send my account validation email...
