Warning: Using this program and the DLC packages that it generates will almost certainly cause your profile to be reset at some point. To avoid this you will need to deselect any custom rider/vehicle skins from the in-game Garage before you remove or replace any DLC packages. If Reflex tries to load a skin that is no longer available to it, then the game will crash and your profile will be reset. 

please unequip any skins that are in DLC014 before installing these skins. if you happen to screw up your data base folder the solution generally, is to reinstall the last gear you had so that it can be unequipped.  Although you may still get other problems where you cannot change skins at all, and therefore will need to reset your profile.
