I have WormMM but the maps don't work

[lightsout]

I have WormMM and i made a map... it told me to save it as a png/bmp file, so i did. then it asked me if i wanted it in the W:A format, and i said yes, but it still doesn't work.

Check if the map corresponds to the specifications listed on http://worms2d.info/Colour_map.
