go to your data folder, drag the motif file in there, open up mugen.cfg in notepad, go to where it says motif = data/mugen1/system.def and change that to motif = data/(insert name of folder)/system.def and make sure that the system.def is inside of the folder,not inside a folder inside of that folder.
