Downloadable products download links problem

If you are selling downloadable products with woocommerce, then don’t use this plugin.
because if you remove the email field from the checkout page, then the customer not going to have an email for the order. if the customer doesn’t have an order email then he/she’s not going to be able to download the product links.
The customer going to see this error (Invalid download link. Go to shop).
this problem has happened to my friend’s site and I simply fixed it by removing this plugin and installing this plugin.
