Important Can't Link Steam version

Attempting to link Steam version to site, generates errors when connecting to site, says account linking not permitted. Tried with the "free code" on the profile page in linking with my Advanced steam version and the input code spot does not work, just shows red code.

I would like to know the same thing.

Same here, looks like support here is zero!!

Updated steam invite/code but still comes up with free code Utter rubbish!!
