D:\Program Files (x86)\Microsoft Games\FS2004 is there the game resides.
Same place as prior to reinstall, all aircraft WERE easily and quickly modifyable.
After install, problm arises.
Just a thought. Which text editor are you using to edit Aircraft.cfg?
TxtEdit ------- Version 4.5.2
What happens if you edit a copy of Aircraft.cfg outside the FS2004 directory, adding the repaints before pasting it into the _Spartan folder?
Bear in mind this is ANY aircraft I try to edit now. Not ONLY the SPartan. ALL my Owen Hewitt Bell 206B III Jetranger folder airfcraft (2 folders many aircraft, all B206B_III from Mr. Hewitt) vanished when I tried to edit the Megapack ones only. They are in two separate folders, but the only real difference, not counting ui_variation= , is that one folder was ui_type=206B III Jetranger for the megapack folder, and ui_type=206B Jetranger III. I split them off because it seemes like people who do textures for Mr. Hewitt's B206B III use one or the other. And there are SO bloody many....
ANYHOW...I drift...
I don't know yet. I have to help clean the fish tank today so we can reinitialze that. Total stripdown, scrub and restart. No fish atm so no worries there...But I will see this evening, one way or t'other and post the result. Thank you for the idea!

BTW: I reinstalled FS9 right back into the same folder (see above) as the one I uninstalled. I used teh boxed disk to uninstall and reinstall, but the folder remained after uninstall, so i just reused it. Could THIS be the problem? Should I just uninstall, delete alll that remains afterwards, make a new folder and install into that? Be just as easy to make it D:\FS9...?
And a gentle reminder: I am using Win Vista Home Premium as an OS. It's what came with the comp, and you know how twitchy Dell computers can be about OS installed...Rather not go through changing it atm...

Please feel free to keep prizing info outta me, SOMEthing has to give eventually! Use a crowbar if it helps, or a nice tug from a carrier....Heck, at this point I am open (pun intended here) to trepannation!

Off to clean fish poop and hardwater deposits...
