Can't download Cubase 9?

Hi,

I have been trying to download Cubase 9 over the past couple of days and for some reason when around 2.51GB of the 10.5GB file I get “download completed”. However, when I try to open the zip folder I get :-

"Compressed Zip Folders Error

Windows cannot open the folder

The Compressed (zipped) Folder ‘C:\Users\Richard\Downloads\Cubase_9_Installer_win.zip’ is invalid

I’ve tried using a file donwload manager (Chrono) but this has helped. Please could you help with this issue?
