Problems with map2dif and TGE 1.5

I'm having some problems with map2dif. Even with the simplest map I can make, Torque crashes when trying to load the resultant dif.

I'll keep looking and try and figure out what is wrong with the dif I am getting, but I thought I would post in case I'm doing something obviously wrong.

I'm also a little unsure if I am using the right version of everything. What is the difference between map2dif and map2dif_plus? I'm using the map2dif_plus built from the 1.5 SDK, I had to add the lightingSystem files to TorqueToolLib before it would even build, and that doesn't inspire confidence. :)

Thanks!

Here's the map file (a big cube):

{
"classname" "worldspawn"
"min_pixels" "250"
"geometry_scale" "32.0"
"light_geometry_scale" "32.0"
"ambient_color" "0 0 0"
"emergency_ambient_color" "0 0 0"
"mapversion" "220"
"wad" "\torque\sdk\example\gameone\data\interiors\gameoneint.wad"

}
}


Here's the output of map2dif_Plus:
