Ok, English is not my first language, so maybe I need a translator.
Can you please explain this:
Do you think is better to set a product for unlimited download after purchasing or set a limited number of time they can download it?
Actually I use to set "unlimited"
Where do you see an option for "unlimited" or "limited" downloads? Where do you "set" unlimited?
Because to my understanding of English, by saying "I use to set unlimited" you did in fact claim to be able to do so.
