yeah, it doesn't work
I don't know if anyone had tried this before, i guessed it would not work, but when I found my mmf1.5 disk I had to try it for fun
mmf2 throws an error msg about incompatible version etc.
BTW mmf2 is WAY better, hands down. the 1.5 interface felt really clunky in comparison and the properties area is much more advanced in mmf2, and there is more control all over the place. it was fun to go back and compare now that I have been using mmf2 for some time now
