[Remere's Map Editor] Problem while adding new brush

[klekSu]

Hello!

I'm having problem while adding new brush to the RME. I've created a new item and tested it, it works in game. I'm trying to add the item now to RME and woah, seems like it isn't working.

I've pasted new items.xml and otb and added a brush like that:

	<brush name="upper lava" type="border" server_lookid="11389">
		<item id="11389" chance="10"/>
	</brush>

	<tileset name="Cave">         
        	<terrain> 
			<brush name="upper lava"/>
	        </terrain> 
	</tileset>

Sadly it's not working, in return it gives me this.

How can I make it work?

EDIT: Oh I had to load new sprites to the editor, ok nevermind thanks!
