Version 2.0 separates the server from the client. Now when a race is selected you will jump straight to the race, instead of being loaded into a second window to race. The Client now handles everything that deals with the accentual racing of the game.
Now all you have to do is buy your car, and select race. A dialog will pop up asking rather you wish to race single player or Multi-player (Multi-player is not enabled in Demo). Click on Single player and another dialog will pop up asking you for a name, and Track Type you wish to Race on. Type in your name, and select your track. Hit Ok , you will be dropped into the race, and off you go.
