I bought this game on Direct 2 drive for $20

I tried playing and it said i needed a username and password so i made a Station account

I entered  the Code they E-mailed me and it said i got 30 days of play

Then i tried to play And it said I couldn't and my account was disabled since the code is unique i cant use it again ( i didn't Try to i just thought ahead) So did i just Waste $20?
