If this is for your own use then the Author or Distributor certificates really do not matter if you make new ones.

If this is content published to the store and you forget the author’s certificate you cannot update the content. You would need to create a new content and suspend the old one. The Author Certificate tells the store who created it and they must match in order to prevent hacking of someone else’s product.
