Why tilesets don't work

Why sometimes tilesets don't work and have black tiles...how I can solve this problem

[magicwhistle]

check the filename of the tileset youre going to use,
Create an NPC in your level (which looks like a transparent person at the right hand side, under the NPCs, baddies tab), and then type the following code into the NPC:

//#CLIENTSIDE
if(created){
removetiledefs;
addtiledef NAME OF THE FILE,,1;
}

The tileset should load if you have it in your Graal folder.
