recently with the v12 patch i got this message when i tried to launch a LAN server game :
CD Key authentication invalid for internet servers.
So i update in v13 but the message still here and i cant play...
Some help please
I installed the game myself so to see if there is indeed such a problem with the current patch. After i installed the game and the v13 patch, i was able to play both online and offline.
What i suggest you is reinstall the game (our release) and then the updaye patch v13.
