Too large maps?

Too large maps?

Hi, there...

I've created 7 costum Warcraft 3 - Frozen Throne maps, connencting them with a Champion. As I started the champion with the first map (=visible), it won't start (the game returns me into the main menu window)...
Each map has a correct "Next Level" Trigger.

- My guess is that my maps are too large, since each takes about 70MB space... Is that it? Did anyone had similar problem?

If they are in a campaign, make sure that you have it as Set Next Level to MapName.w3x, not Maps\MapName.w3x
