Its important to leave the new texure folder named as it was from start,unless directions tell you to change it then make sure your new text entree in aircraft config is the same. Also leave space between each text config. Check your aircraft config entrees from the top and make sure you duplicate the space and ,if any lines them as well. Make sure you backup before any change is made. Sometimes texture folder will have name but not the text in aircraft config and thats ok.The aircraft config entrees should always be in numerical order, 1,2,3 and so on. Hope this helps.
