i have to agree with youDon't take this the wrong way, but you made a mistake. You should not have deleted all your old content. You should have just created a new channel for the new content. If I were you, I would re-upload all the old content (I hope you made a backup) and move all your new content to a different channel. I know building a new channel seems like a big task, but it is a whole lot better than killing a successful channel with 32K subs.
I hope it all works out for you.
