Hi Ron
Go into your aircraft folder, copy and past on to your desk top the plane folder you want to repaint. lets say the SE5-A,open it
now remove from the folder the thumb, preview, and the SE5A TMT file only an delete. Now on your desk top you will have the new repaint folder open it up, copy and paste or drag an drop all the new repaint files into the SE5-A Folder. Now this will take a little bit of time so take your time. lets say the new repaint is called SE5_A b and you have to rename these files, the preview text document,TGO file,TMG file,TMD file, with exactly this SE5_A b. Now for the next bit open with note pad the TMG file at the top type exactly SE5-A b.tmg
then the next line Geometry( "aircraft/SE5-A b/SE5-A b.obj", "Fuselage" )and keep going down the page thus there 4 pages in this file to do when finished save it.
the next file to do is the TMD file open with note pad again, at top type in file: SE5-A b.tmd and save. thats all you have to do in this file. now close the airplane folder and rename it exactly this SE5A_A b now you can put it back in your aircraft folder or use the AFPD IMPORT WIZZARD. an your ready to "rock an roll"

P.S. You dont have to type the whole line just space then b after the -A Thus SE5-A SPACE b


Hope this helps Ron
