Aerosoft airbus extended x problem

Hi all, i have the Aerosoft airbus extended x and it all works fine, until i installed a couple of air New Zealand liveries and from the outside they look great, BUT in the vc there are no textures. The vc is fully black even the windows are black so you cannot see anything through them. It must need something in the texture config but im not sure. thank you all for any help i would appreciate it.
