I bought the game from game stop. when i try to play the game i get the welcome box that says this software must be authenticed etc. i click Next i get the box that asks for my SERIAL i put in my SERIAL and click activate it does the activation in progress and i get the Activation process complete, unlocking your application with an X next to it . A box pops up and says Activation Failed: Activation process has been terminated. The SERIAL was not found in the database. Most likely the SERIAL has been entered incorrectly. (which cant be because i copy and pasted the Product Code). Press Back to retry activating or click 'Cancel' to abort. I dont know what to do this is all i get when i try to play.
