Map size problem. :(

When i make a map in Editor and the map gets the size Epic, then when i test the map its say: Map is too big: or something like that. o_O

Can someone help me here?

All I can say is wtf. Report this to blizzard, ive never had such a problem.

Do you test your map on Battle.Net or LAN ?

In multiplayer games u cant play a map which is bigger than ~ 5 mb ( i dont know)
