I've re-textured a car and replaced the old texture with the new one but it won't work.

ProwarfareZombie The car I first re-textured is Cell car A however I can't seem to make the new texture replace the old one. I've managed it perfectly with The Family Sedan. Can someone help me out?

97Meter I cannot be of much help since I am a beginner at this. You should probably go in more detail so that someone more experienced than I can help you.
