Issues with Download Assistant (Cubase Pro 9.5)

I have purchased Pro 9.5 (update from 9.0), and I downloaded and installed the Download Assistant.
I started downloading “Cubase Pro 9.5 - Update from 9.0”, and once it finished, I had a blue bar starting to move back and forth, as if it was loading something. After hours, it was still doing it, so I deleted the files and started downloading again the 9.5 setup software.
But now, this blue bar has been moving back and forth for almost 24h and nothing has changed.

Anyone knows how to solve this issue? Is there an alternative way to download the update?
