You need to open one of the levels that is in the gmap and then in a blank npc you need to enter the addtiledef script that konidias pointed you to in your other thread. Then it should apply the Zone tileset to all the levels in your gmap. The levelgenerator will create them with the old tileset, so you'll have to make it a bunch of blank levels with all grass (if you use other tiles it'll get messed up). Once you have applied the zone tileset to these blank levels you can then edit the whole gmap with it.
