Midi Ringtones Sound Funky

[KilgoreBA]

My Midi ringtones for my xv6800 were working just fine yesterday. Today, when somebody tries to call me, they don't work. I had certain Midi ringtones set to individual contacts and a general Midi ringtone for anybody else. When I go into Settings, Phone and listen to the different ringtones, most do not work while others sound really strange and garbled, as if the device were under water. Any help on how to fix this other than Hard Resetting, would be greatly appreciated.
