Those files refer to the background textures inside the sky's geometries. You must either add the necessary textures to the track folder (or mas file) or edit the geometries and replace them with new ones. This is a common error that comes from people simply transplanting an existent sky file from another track over and neglecting its textures. Or could be an issue with the scenery files not pointing towards the correct mas files and/or its right path.
