Files Tab On Product Details Page

Version 4.3.3

Okay, have upgraded to 4.3 a while ago but I've not added a new product since doing so.

Where did the Files tab go for adding files to a product for EDP distribution (Attachments are there, but not Files)? I used to have a Files tab on my products that allowed me to have a different archive for different versions of the cart.

But that tab is gone.

I have fulfilled orders that use this for existing products. However, there is no Files tab for those existing products nor a new one I'm trying to create.

What am I missing? Is there some new setup option that needs to be selected? Or is there some missing component preventing the files tab from being shown?

Never mind. Apparently there is a new setting to enable selling downloadable products that was unchecked.... Grr....
