it basically when you install kung fu rider externally to usb, it will make all your games disappear when either backing up or loading into backup manager with it installed, even though the space taken by them is still gone on your hdd, what is even worse is that you can't access them on a pc either, it's almost like it's altered the whole hard drives file access, this has happened both in the latest multiman and rogero manger so i thought i would warn you all not to install it externally, also it has happened to me three times with the same game, so i doubt it's a coincidence
