Hello everybody!
I downloaded Cubase 8 Pro Trial version (30 days free),
but after installation, it opens not and asks for code activation.
Then I bring in the code sent by steinberg in the center elicenser, but nothing works!
I read as this trial version works only with a key elicenser, is it true?
Because if it’s true, I find stupid to have to buy a key to try a free product. 
Its true, Cubase 8 Pro trial needs the eLicenser dongle. Cubase Elements trial does not. See here…
