Making a multiplayer map

[mapmaker]

I've made a few maps, and they work fine in single player, but when I try to load them up in multi-player, it says the file cannot be found, etc.
Does anyone know if you have to 'flip a switch' so to speak, before you start making a map, to get it to work in multiplayer, or am I missing something?
If anyone can help me, I would greatly appreciate it. I have a great idea for a map, but can't start on it without knowing the answer to this question :)

Thanks.

To make a multiplayer map go to the file menu in the command bar. Select load project. Go to the tools directory and select the StarWarsMP.qe4 project file. Now make your map. On a related note, make sure that you have the updated version of the tools, since the initial release did not contain a path leading to the entitites.

Thank you VERY much. But where might I get these updated tools?
Also, will the MP map be backwards compatible? In other words, can I play it in single player too?
Again, thanks a ton.
