Zeroeditor can only load worlds that are located in a subdirectory of the editor

[Snake]

So with the discovery that SWBF is on steam me and some of my old friends decided to get on and play a little bit. Well, naturally I thought about modding. I managed to download the ultimate mod tools but when I try to load a stock world into zeroeditor to refresh my memory on how things work it gives me the error: "zeroeditor can only load worlds that are located in a subdirectory of the editor" even when I put the world file literally next to it. Not sure if it's an issue with the steam set up or using "Snake's Ultimate Mod Tools" but if anyone knows how to fix that please let me know. 

--Edit

I found a workaround by placing the shipped world assets in a custom world folder and then loading the shipped .wld file.

Try using this version of BFBuilder

make sure there are no spaces in the folder you install it in.

C:\lucasarts  is the best place

Also, sometimes it will do it regardless. Quitting then restarting the program usually solves it though.
