same problem with me.. any solutions? I have downloaded complete data by game it self.It refuses to play. I did everything as per instruction, but I start the game, and when I try and start a race, it say "Game requires wifi connection". If i connect the game, it says "New update ready to roll out. Please update before you can play the game." And that message cannot be removed, until i go into the play store and there is no update icon. If i turn off my wifi, and try a race, it then says "wifi required to play". Haven't tried it on multiplayer, just the normal game mode. I'm hacked its not working.
Can you help?
