Gamepallete...whatever refers to a file that wasn't included with retail FS2. I think it has something to do with subspace missions. Anyhow, the file is in the Core Media VP, which is located
here. But to get it to work like its supposed to, you may want to grab FSOpen 3.6.
Details are in this thread. If you grab the full installer one, it should have all the VP's you need. There's also some new version of FRED you can use, but most are pretty unstable at the moment. I don't have a link handy for that one at the moment.
And just a word of warning, most new FREDders come around announcing a huge campaign, but few rarely come through. So don't be surprised if some people aren't super excited about this. It's advised that you either join a project start off small like a mini-campaign or something. You don't have to, its just that if everyone worked on their own huge campaign, nothing would ever get done.

If you're just starting to FRED, I'd recommend checking out FRED Academy. It's geared towards the new FREDders or people with little FREDding skills. There are more details about it in the thread at the top of the board.
And finally...
