Here's an easy fix for the "not being able to save anything" problem

You can download a program called Audacity for free off of their website. It's basically just a recording/ Mixing program.

What you do:

1.) Download that "Ableton" program
2.) Make your beats
3.)Get a line in/ line out cord
4.)Hook that up to your computer's output/input audio ports
5.)Set up the recording input on Audacity to your compy's line in
6.)Hit record on Audacity before you play your beats on Ableton to listen to them
7.)And there you have a save-able file that is your original beats

Personally, I have a mac so I just use Garageband for everything. SO EASY TO USE

But it's not free if you don't already have it on the comp...it's standard on the iLife '06 and up macs
