Cubase 11 upgrade from 8 is not working

I do not know what is wrong. But I have purchased Cubase pro 11 upgrade from Cubase 8. I have paid 250 euro for a product that is not working. I have submitted a ticket some days ago but no answer.

Is this how Cubase supports performs? I had no issues with Cubase 8 in years so it is my first time contacting support. very dissappointed!

How is it not working? Do you get an error message?
