ok got ur map.
looks ok to me so i can think of one thing: did u export the map aswell?
File > Export > 'firstmap'
this will add a .bms file in ur DFLW folder. this is the file that the game reads - not the .mis file.
also i noticed u set colour to 'Alpha'
this will make the game not render textures and everything will be invisible! plz choose one of the other options m8
