Can't make any GT3 paintjob

Hi,
I tried to make a new paintjob for a championship with GT3 Challengers Pack but I can't. It works with other cars (Porsche Cup for example) but not with any GT3 car. I make the new folder with Create, the folder is there with the paints but the game can't see it.

 

In the Showroom did you press Reload and then maybe the Variants?

 

I make a new driver. The variants are showed but not the new driver.

 

You may have used the same name from a previous skin.
Try using a different name.
