I can't remove a ringtone from LG 8100

My darling baby girl was playing and put a whole song on my phone as a ringtone and now I can't remove it. I really don't want to use up all of the memory in that section as I do not put the ringtones on my SD card. I am using the latest BitPim. Any help would be awesome.

Thanx

Sorry if this sounds stupid I do not mean it to but on mine when I am on said ringtone that i put on there I click options and delete is there.

I have an 8300 though so....
