Skittles,
If Moach's suggestions don't work for you, then you will need to check a couple of things in the aircraft.cfg. (If you don't know how to do this, then you can open it up in Notepad, but make sure you take a backup first.)
- the "title=" line in the [fltsim.x] sections all must be different, or else the repaint with the same name will not show up
- the "sim=" line in the [fltsim.x] sections must be exactly the same as the .air file name, minus the .air extension - or else the plane won't show up
- check that the name that you expect to see is in the "ui_manufacturer" line. For example, sometimes tha plane designer will put their name instead of the original real plane maker - so in the FS listing, you might get something like 'Project Opensky' instead of 'Boeing', so you need to check your listing carefully.
