One white car

I have a small problem. In the game everything is allright, except one car, the Honda from Barrichello, that one is white. Button's car is normal. How can I solve this?

You probabely have received the honda that rosberg converted for his mod and there was a problem with the second lod at the first release of the car. So you'll need to get your hands on the update, best is to ask rosberg himself to send you the latest version if he wants to share it.
