As far as I can see your FAF account is not yet steam linked. So even if you fix the UID related issue, you won't be able to log in. In the privacy settings you need to as Philip described set your owned games (not just profile or inventory) to public. You can disable this after you completed the linking process on the website and the FAF API has verified that you own the game.
If you encounter any error, please post it here. If against all odds your are still unable to link your account, add me as a friend on steam and send me a message, then I will see if I can manually confirm your ownership of a steam copy of FA.
