[CLOSED] 'player key was not found'

Hi
So i bought pcm 14 today in a store on a cd so not on steam.
There a code on the manuel called 'product code'
I used that code to activate the game and it worked.
But when I create a profile on pcm 14 and i put that same code in the player key bar and i go to multyplayer,
it says "player key not found".
I have typped the key correctly and that key is the only key i have.
Please help me
thank you
