Hello. Please help! 
I have just upgraded from Cubase 9.5 Elements to Cubase 14 Artist.
When I came to install the new version of Cubase, the Download Assistant opened up but would not allow me to download Cubase 14 or any of the related software and content. Please can someone help resolve the issue. 
Scroll down a bit. There’s only the one installer for ALL versions.
Did you receive a download access code and, if so, did you enter it at the top of the Download Assistant window?
