Start the game either single player or multiplayer. On the opening screen in the bottom right corner should be the version number of your game. Seventh patch was the last one called 1.6 to 1.7. This gave you a patched version no. of 1.7.1263
What version number you got on your game?
If your not sure what patches you have applied, I would suggest you d/l them all and install them in number order.
