Ring Tones

I have a blackberry 8530 curve. At one point I had ring tones setup for certain people so when they called me or sent me a text their ring tone would go off. Now I have the ring tones set for that, but only if the user calls me does their ring tone work. If someone sends me a text message it's just my regular ring tone instead of the ring tone I selected for that user. Any suggestions on what could be the issue? I get my free ringtones from myxer, and some of the users ring tones work just fine but some don't. I know it's not crisis issue but I just don't understand WTF happened?

Maybe just reset the tones. Maybe something just got messed up .

Do you have hyphens in the phone numbers in the Contacts list?
