Sometimes when I make ringtones for my phone and try to send them via bluetooth, I get an error message. I have been able to make about 6 ringtones but no more. I don't think there is any kind of incompatiblity issues because all of them came from my music library on my PC. I have ripped one from a CD that I bought and it worked but I did another one the same from a different album that I bought and it won't work. These are not downloaded from itunes or a burned CD. Can anyone help me figure this out? Thanks.
