Hi aal i have now the s2 licentie but if i want to race i cannot select cars i have only 3 cars can anybody help me??

have you activated your game yet? doesn't sound like it atm..

Try clicking the unlock button on the main screen, enter your game username and password.

And if you've done that already, make sure to choose "S2" at "Online Mode" in the multiplayer screen before you click "Show Server List"...
