I would suggest creating a new channel because adsense appeals are nearly impossible. Just create a new channel, drive you audience over to the new one and when your stats are built up apply with a network to be partnered(if like to be partnered) such as Fullscreen! I would even say just move all your content over to your new channel also and delete your current one.. Its a good way of starting fresh. I my self had the same thing happen to last fall and i was partnered! i had to start a new channel, worked my butt off with videos and content and applied with fullscreen.. its going to be hard, but as long as you stick with it and the help from the forums youl be back on your feet in no time at all!
