I create a map without changing the sides or going into zeroeditor to change add objects or new terrain. I munge it and then I go to the game and launch my map. It loads fine. When it is done loading all your units show up. I click the Assault Trooper and I click spawn. BUT IT DOESN'T SPAWN!!! Can some one please help me with this problem and have a solution, thanks. By the way, how do you delete maps because I have too many? That might be the problem.

Welcome to GT!

As for deleting maps, go to C:\Program Files\LucasArts\Star Wars Battlefront II\GameData\addon (or C:\Program Files (x86)\LucasArts\Star Wars Battlefront II\GameData\addon if you use Vista/Win7). See all those three-letter folders? Those are maps. Delete whichever you don't want to keep.

Note, if you use Vista/Win7 some maps might also be in C:\Users\Username\AppData\Local\VirtualStore\Program Files (x86)\LucasArts\Star Wars Battlefront II\GameData\addon.

Hey, thank you for telling me how to delete maps but do you know anything about the other problem I have?

1) welcome to GT
2) can you post your LUA?
3) enjoy your stay

he said that he hasnt changed anything, so i would believe it is either a munge error or that he has too many maps as previously stated. just delete enough to where it doesnt say you have exceeded mission count and you should be good.

If he's exceeded the mission count, then BF2 would crash altogether.

I deleted my maps so it is not exceeding the mission count. But I still can't spawn in my new maps! I really want to make a map that I can actually play!!!

You weren't exceeding the mission count before. Do your command posts show up? How fast was your munge?

The command posts don't show up, when you select your unit, there is just a blank map that's gray to the left where the map usually is.

A similar problem was reported here. Try a manual clean like that person did.
