IF ANY 1 KNOWS ANYTHING ABOUT HOW TO CURE THIS PROBLEM PLZ REPLY thanks
There is no cure.Contact the customer service department at valve.Steam has an online verification system so There is no way around it unless it happens to work somehow and it doesn't appear it will.
No, you'll need to take it back to the shop or ask help from Valve...valve will most likey ignore you so take it back sayign the serial doesn't work and you want a NEW copied...it will only work if its NEW
