Can't change to custom Livery

[Westbeef]

Hi,

I've made a livery for a Caterham 7 and whenever I change the livery and go back it changes back to whatever it was previously :/ I can't get it to stick with the custom livery.

It works.
After pasting the files this is what I get
* when choosing livery before confirming it with clicking green circle


* after confirmation, in View Info shot


* and on track (solo race)
