I just bought my Bioshock from New Egg.New copy.Downloaded,but cant play.It says something about a serial number.I am lost on this.All I want to do is play my game.I am giving this troubleshooting thing 24 hours and I will send this waste of time back.I hope someone has a solution because this disc is about 20 minutes away from being smashed and incinerated.It just might be worth the 20 dollars I paid to see it destroyed by a hammer.
