Blues Racing

I downloaded the new pack 4.1 and for some reason the only Monster Energy truck is the Graves Monster Energy. Do I have to clear cache, and regen? I have tried that several times. I have deleted version 3.2 and it keeps coming back and it appears back in the vehicles folder? I want to make sure I have all the trucks in version 4.1, and all the new updates, such as the redeigned handling trucks? If anyone would help, it would be appreciated. Thanks Jason
