HI, @Keith Harrison! We have a daily download limit of 20 GB in place for a couple of reasons. Moderating downloads helps relieve stress on our servers, ensuring the website operates efficiently and smoothly for all users. But mostly this in place due to bad actors who purchase courses with the intent of downloading all materials and then requesting a refund. This is known as "wardrobing" and limiting daily downloads helps us to detect and eliminate this type of fraud.  If you have a special circumstance reach out to me at support@proko.com and I will try and help! We appreciate your understanding!
