Motorola V220

Anyone know what's going on here?

I've got a V220. Setup the phone directory with personal polyphonic ringtones for friends & all was working just peachy.

Last week all my personal polyphonic ringtones dissappeared and were replaced by a bland "ring ring". The default polyphonic ring is working just fine. I can change the personal ringtones to some other non-polyphonic ring and that works, but...
I want my polyphonic ringtones back.

Help...
