Having trouble downloading 8.5 pro from serve, timed out?

, I have a quick question that you could possibly help me out with when downloading softwares that hold a lot of gigs such as recording softwares off the web. I bought cubase 8.5 which about a 10 gig (8-9 hours) download, my internet starts to download it and then about 4 hours into the download it stops downloading it and says something about server timed out etc, how can I fix this or how can set the server to where it’ll let the full 10 gigs download? I’ve bought the program and can’t even download it, I don’t know much of what to do
