Registration code from Steam denied

Every time I put it in it says denied. Am I putting it in wrong or in the wrong place? I thought I was supposed to put it in when I click online for the first time.

Thanks!

It doesn’t matter when you put it in, but are you sure you are filling it in correctly? I think it’s case specific.

yes try all that you have been given…

i tried three times my was on the bottom of the email (copy and paste won’t worked)

make sure your firewall doesnt block the game. Sometimes a ‘code invalid’ message just means the server never got it. All the codes are definitely valid…
