I have exactly the same issue, I can connect with my email address but not my handle, username or whatever pwe calls it. This is rather an annoying issue. Is there a way to make it work properly or could someone explain what I am doing wrong? Many thanks.
Haven't received any mail either, got in closed beta 3 with a key received from Nvidia, since then bought the 3 founders packs, I guess my account is flagged to participate or should I still get notified by mail to get in?
Just got guardian, essentially for the rank 3 mount. I consider like I paid full price for a regular game. Except I have to wait to enjoy my product... Hope I won't regret this.
