Map2dif not working?

Ok, I know that the forum said not to post this here, but I couldn't find the right place at the art section. I have resently been making a castle model using torque constructor, but the map2dif exporter isn't working. I got it to export once, but then it wouldn't export again, I made no changes. I also don't get any error reports, just a window notice saying that it has encountered a problem. Does anyone have any idea what is happening???

PS: the regular exporter works, just not the map2dif
