Mana Games

Hello
i and one my friend, have this fantastic game from 4 years
We would like to put the game out of Steam, but it is impossible to redeem it, every time we put our key, we are told that it is not valid? why?
What should you do?
If I put it in the cart me do recover again
But we have already purchased years ago
Thanks
