Mine is in the Stock Steam version, which is v1.4b. Yours might be for an earlier version of the game. Each of the Mission Editors only works for the specific version of the game. Also, if you put in a mod, the Mission Editor only works for that particular mod. If there is a mistake in the mod, then you will sometimes get errors when you open the Mission Editor, or if the mod doesn't de-activate properly, it can leave the game in an unpredictable state, and the Mission Editor may throw errors for that also. I do not have my original "StarFarce" version of the game on disk. It is somewhere in the boxes upon boxes of computer stuff I have downstairs in the dark recesses of the basement, else I could look at that version of the Game, but for my Mission Editor, I have "GENERIC" for each of "Escort Carrier", "Destroyer", "Destroyer Escort", "Patrol Craft", "Troop Transport", "Tanker", "Cargo", Coastal Vessel", "Bomber", "Torpedo Bomber" and "Fighter", with the last three being airplanes and the first eight being for ships. Any mod might also change some Type= designations, and have more listings for GENERIC.
If your game is version 1.4b (shows as 1.4.1.1 in Windows Properties), then it might be, from when you attempted to use mods, that with the crashes you experienced, your game might have a bad configuration now. It might be to your benefit to un-install the game, delete your Save folder (defaults to "C:\Users \UserName \My Documents \SH3"), and re-install things "fresh". Just remember to save your edits that you want to keep of the "Campaign_SCR.mis" and or the "Campaign_RND.mis" files.
