Sony Ericsson Z500

I cant seem to get my computer to recognize my phone. I download some files from sony and some others that i read about on a forum. The cable i got didnt come with a CD but it is a sony ericcson cable.

Could anyone who has the cd copy the files off the cd and email them to me please?

or link me to the correct drivers and an aplication so i can send mp3's to my phone to use them as ring tones.

Thanks!!
