I made a new map but it won't show up when choosing maps in-game. HELP!?

[Damned Blade]

I've encountered this many times but was too ignorant to post for help.
Most of the maps i have made (even those not 'official') don't show up when i am choosing maps in-game. They work perfectly fine in the world editor.
pls help!

The name of the file is too long. Try to remove few letters until it shows up.
Sometimes I encounter this too and just use shortcut names (ex: Defense of the Ancients -> DotA).

and remember that folder names (except the base folder which is Maps\) is included in the 32 (I think it was 32) char limit...
