Help me to login to multi player

[Rubicon]

OK, I am really not that stupid but this has me beat. I have DCS P51 and I am trying to connect via the DCS World Multiplayer icon.

 

I get asked for a username / password but it just rejects my input. I am using the same U/N and P/W I used to buy the game. Am I missing something?

 

Help me get in there - you will get free kills until I learn it :D

Is it the same username and password used here?
