I had that problem before because I logged-in the game's lobby with my e-mail address. Here, I'm "CyberMage", and I can also use it (instead of the e-mail address), because it is my Impulse nick (as well as my forum nick).
So, instead of logging-in with your e-mail address, use "Freyar" : it will work if that is your Impulse nick.
To quote another poster who helped me, you can always change your Impulse nick (without changing the account's e-mail address, of course : that you should not do!) there :
« Open Impulse, Click Community, Make sure you are logged in, click My account, then Login....and then you should see the change username button. »
When I first went there, I saw "CyberMage", so I understood that I could log-in the game's lobby either with my e-mail address OR my Impulse nick (which also happens to be my forum nick).
(In a game, it was silly to see that my Queen of Thorns had a Hotmail address (with the @ !) as her name. Now, she's called CyberMage. I could always give her a feminine name by going into Impulse, before launching the game, to change my Impulse nick. But that's too much trouble.)
