Download Failure for Cubase 11

Cannot download Cubase 11 from Cubase 10.5. I’ve tried all download links without success. I get the following message:
Steinberg Cubase 11 installation failed.
An installation package for the product Steinberg Library Manager cannot be found. Try the installation again using a valid copy of the installation package “Steinberg Cubase.”
I don’t understand the problem. I’ve updated Library Manager, etc. Can anyone solve my problem?
Many thanks!
