Loading Problem

So i'm making a map for my campaign, and everything is going fine. I update it one time and check that the button says the map is connected to it. So i go into warcraft 3 and try out the campaign, click the button expecting the map to load, but the screen goes black, then reloads the level select screen. I went back, deleted some non-needed music files so the map was under 4mb, but the same problem occured. Whats happening?

EDIT: nvm i figrued out the problem
