i keep getting an pop up when i start morrow wind and it keeps telling me that the chunk is too big maz is 8 any way to chang this so i can play marrow wind on my laptop running vista

I get that one with my level list merger. and it usually says something about converting to z axis. which i believe is for the database the mod made. if you just click yes on continue running script. game should play just fine. i usually get that one twice. each time i start game.
