Sorry I could't reply sooner, was getting late where I am. From your screenshot, you don't have a game registered to that account on any platform (PC, PS3, PS4) and need a valid registration code. Since the one you paid for seems to have been used, you will have to contact the people you purchased it from. This is going to be a bit tedious I imagine. The distributor will most likely send you to SE and SE will most likely send you to the distributor.
