LG AX565 and BitPim

Hello everyone,
I'll start off by saying that I just got my first cell phone about 2 weeks ago, so I'm not exactly handy with some features yet.
What I'm trying to do now is use BitPim to put mp3 ringtones on my LG AX565. I've heard it's possible, but I can't figure out for the life of me how to get it to work. I have a USB cable for the phone, and I have downloaded BitPim. I've tried getting a driver, but what I'm doing doesn't seem to be working.
If someone could post a detailed, step-by-step instructional for how to do put mp3 ringtones on the AX565, starting from getting the driver you need, that would be really helpful.

Thanks!
