BMW i8 – 1.3.3

Stefano says:

I installed a PURCHASED CityCarDriving last release (1.3.3) and downloaded your BMW I8 mod, but the game unusually crash; always.

I note in the trouble message (…D:\Transporter\Tools\CEGUIscr\RenderModules\Direct3D9\CEGUIDirect3D9Texture.cpp…etc..) that the resource invoked are not “absolute” but the mod (BMW I8) refers to file paths NOT on my PC, but may be on some your development machines…

How can I solve this problem ??
(I provided off course to properly modify data\config\player_cars.xml file so to have BMW-mod-code at bottom of file, just before LAST tag)

Must I pay to play this BMW I8 mod ???
Thanks for your reply.
