Where did my mini map go??

There's no window for it on my screen whatsoever.

This happened to me, try relogging a few times.

try click-dragging toward the center of the screen from the borders of it. once i lost mine and it ended up being way down at the bottom with a barely visible border but was clickable so i could pull it back up

You can also try a clean install of maple. That should reset window positions.
