I got 2 network errors over the course of downloading, but still managed to get it all downloaded over the course of 3 hours yesterday.
The difference between the Adobe download the OP references and this download is that Adobe uses a download manager that can resume downloads if there's a network hiccup whereas Cakewalk expects 2-3GB files to download uninterrupted. I got to 1.9GB on 2 different files before they crapped out last night, which was a waste. Adding a download manager to the website would resolve it.
