Bought DVD version of game here in the Philippines. We have bad internet service here so it took me awhile to load everything. I finally got all the patches loaded and when I started the game I got the picture with the knife through the saber toothed tigers skull and then it quit, no game started, I tried again and again no game what gives? I have 12 gigs of ram so I should have no problems since I also have the recommended hardware. Please tell me hat to do to play the game.
