Campaign editor problem ...

Alright, the problem is this :

I added my map in the campaign editor. When I test the map using TEST MAP or CUSTOM GAME it works fine, but when I try to load the map with the CUSTOM CAMPAIGN it just goes back to the Loading screen with the map choices and shows no errors whatsoever. So what is this?? I tried this with a Melee map and the map loads fine. So is there something I should do for my map to load correctly in the campaign?

I have exactly the same problem :( What could I do?

Is it to big? or is there something wrong in the editor like it cant find something? if not then im not sure usually its because it is to big :o

Thanks, the two files were in fact to big. I imported too much mp3s, I think. But why does the size of the maps in a campaign matter? That's stupid :<

Yea that is kinda annoying because most people overdo there maps trying to make it unique and special then it shows up to big
