MFA's saved inside Fusion 2.5 will not be able to be opened in MMF 2.0. Always ensure you keep backups of your MFA files, whether it's dropbox, flash/usb stick, another hard drive or on a server. Once you save an MFA in 2.5 format, you will not be able to open it in 2.0. Before importing ANY MFA from 2.0 into 2.5, ensure you BACK UP your current MFA.
