I Need Someone with a PC and/or More Technical Expertise to Help Me

This would be my first post actually requesting something of my...I'm gonna say, 6-7 readers? Yeah, something like that.

So I got this keygen for a music program I use called Ableton Live (specifically for version 7.03) and it only works on PCs, as it is a .exe file. My old version gave me the inevitable "copyright protection violation" message and shut down just as I was about to add the finishing touches to my newest track (as of yet untitled). This was verrrrry frustrating to me as I have not made a new song in a while and this one was feeling all sorts of fuzzy and special to me. So, if anyone has an operational PC and a few minutes let me know so I can send over this file and have you help me out! It's super easy, should just require you to open it up, send me a number, then have me send you a number which you type in, and then send me whatever number it generates from mine. Make any sense? I promise it's easy...help me, I'm all super sad and stuff.

Easier still would be if someone has an operational version of Live 7 for mac and could send it to me or just tell me how they got it working. Oh! And if anyone's got a Demonoid.com account and wants to invite me, that'd help too!

To conclude I'd like to pose a question: Why is it so hard to get expensive things for free?
