Mpc 60 II 3.1.. loading errors please help

every now and then i when i load a floppy disk it will say this file was created by a unit with a later system sofware version must upgrade. usually it happens when i load the program. but this time its the sequencer.
Please help

Unless you made the beat on a V 2.12 or later or something like that it shouldn't have a problem.

exactly lol what happens is every now and then it will trip out. i got it back in '98 i'm thinking i need to get a cleaner. do they still make floppy disk cleaners?
