Problem signing in

Hi, I have just downloaded Audirvana Studio 30 day free trial and am now trying to sign in. I have entered my email and password but cannot see another button to press to Log In. I am using a small 7" monitor (it’s been ok using Foobar to play my music) and do not know if I am missing something at the bottom of the screen. Any help would be appreciated

Is there anyone on here who can describe what is on the log in page, I have a black box/rectangle, this takes up most of the middle of the screen, inside are two white blocks, one for my email and below one for password I have completed these, but cannot see a button to press for log-in

Just hit enter after putting in your details. The screens take awhile to load so be patient as well.
