Well I just got home a little while ago and started the install of FarCry 2. At the end it asks you to activate with your serial #. It keeps saying invalid serial. I have tried the described manual activation process and it still says the same crap. I am not alone either. My father is also enjoying the same problem. Going to try it on 3rd purchased copy on my kids computer next. As it stands now we have 2 of 3 copys that will not activate. These were all purchased retail from Gamestop. If anyone has any ideas that may be helpful; I'm all ears. Any help would be greatly appreciated.I hope this isn't my reward for buying another Ubisoft game. Anyways, please help.
