dead security key cant sign into account

Hello, I was a old player back in the early days of the game. I bought the delux version with the box and all. 
I had a security key. 
Now I was thinking of signing in and trying out the game.
Retreiving the password and typing the new password but leaving the security key space blank gives the following message:

"Account security key, display name, or recovery code is invalid/expired"

So what do I do, no password that I know of and cant retreive it?

/best regards, David
