Map loading problem

[Shady Guy]

I made my first map, but when i try to run it it doesn't load and just sits there saying 'waiting for server' in the loading bar, i waited a while but the bar didn't move, and it only happens to my map, is there any way to fix this?

No edit button ;(

It also sometimes says 'loading mission' and gets stuck there.
