Everything over at the SE forums just seems dead. I tried to sign up for a free trial while they sort my account out but they don't send out an activation email.
It feels like I'm using Netscape Navigator back in the 90's trying to lodge a support request and I didn't even get a confirmation email so god knows if it went through.
I've even tried downloading the 'demo' version via Steam and going through the in-app sign up process stops at "we sent you an email to activate your free trial" as no such email arrives.
How are new players supposed to get into the game? It seems impossible.
You won't go anywhere through the fourms, you'd have to go directly to support to fix the issues with your old account. If you dig enough you can find actual phone numbers if you want to deal with it that way (it does speed things up considerably faster, but you do have to pay for call costs).
As far as I remember, I got confirmation emails whenever I had to lodge a support ticket. And as far as I'm aware many people seem to be trialing the game fine (recently). Do you use Outlook.com or GMail?
