Ok, here's my questions:
1.) Is this a map you created, or that you downloaded from somewhere else? This will help us isolate the problem.
2.) You say this map is not showing up in Instant Action. I am thinking since the addme did not work, that the map and files are in the wrong place. The file path should be Star Wars Battlefront\GameData\AddOn\ARC(name of level)\addme.script. If this is not in this folder in this exact way, it doesn't matter how many different files you use, it will not work. There shouldn't be anything inside the ARC folder OTHER THAN the Data folder and addme.script (other than possibly a readme and mapinfo).
