My map won't work on Multiplayer when PROTECTED by WC3Map Optimizer...It works in multiplayer when not protected. I tried checking and unchecking the configurations but it still doesn't work on Multiplayer. Other maps when protected can be used in Multiplayer... Version 4.9 btw.. Try protecting my map using WC3 Map Optimizer and play it through Lan or B.NET you'll directly be kicked out of the [game] room after you downloaded the map.
