Steam Trading Cards not dropping

I’ve played the game for about 14 hours now and I havent gotten any of the steam trading cards from the game. I know that there are trading cards for Hitman 2 and on my badge info it says 4 card drops remaining but I still havent received any.
I have get HITMAN™ 2 – Starter Pack,then past a week i buy HITMAN 2 - Gold Edition.
