What must i do to link my steam account
I can't link my account to steam
Try using a site like this [https://www.steamidfinder.com/], you appear to be inputting steamID64 (Dec), and I feel that is the correct value, but maybe try older formats (you can get them on this site).
Other than that, you'll have to wait for help from guys that know how the process works.
