Instructions:  Save to a temporary place (I use my Desktop) and then go to your X:\Documents and Settings\Owner\My Documents\18 WoS Across America\makes\truck\flcc (or fla)\acc folder, make a new folder called paint# (where "#" is the next number in order of your paint folders, i.e. your last paint folder is "paint5," your new folder should be called "paint6."), copy the files from the zip file, and paste into your new paint folder.  It should work.  If not, leave me a message in my Forum
