I cannot log into the client.

Hi, I have a licensed disc that I bought a long time ago and I don’t have Steam, how can I enter the client in this case?

It isn't possible without linking the game to steam. For more information:

But you can create a steam acc, adding the cd key there should give you gold editing of the game so you dont have to buy it again. Link the steam account to faf and then you dont ever have to use steam again if you dont like it.

@speed2 Thanks, this is useful information for me, I will try to do it.
