please help

What do you actually mean?

If you want to change your ringtone-just go to Tools=> control panel=> telephone=> profile settings then edit... to put a desired tone just select browse and look for your tone.... thats basically it!

I know forums like these are nice and designed to help people and I hope I don't annoy/hurt/insult anyone by saying this:
the manual that comes with the phone is pretty ok and has all the necessary basic information. You really should give a quick browse through it if you are new to the phone type fex. from a basic phone to a communicator or switched manufacturer. It will save you a few tears and give you answers quickly 😊
