I have install everything like it should... When I start RSRBR4.exe the menu load and if I choose a car package other than A8_1 this message comes up "RSRBR4 your installation of RSRBR4 is not valid!!!" But if i choose the car package A8_1 i'm able to load the game but right after the QG load the game close and I get back to my desktop....
What's my problem....
(if I load the game normally I have no problem) and I don't have a haced version of the game.
