Pianoverse not working!!

[genesis1]

Ive just installed piano verse, opened it and selected a piano. But the tabs on the top left don't work properly. I click and nothing happens. I finally hit enter and it went to the piano screen but then no sound and non of the other tabs work like space, mix and effects! I checked before I purchased and it quite clearly states Mac OS 10.13 or later on the specs webpage. I'm running a mac 10.13.6

Found out this afternoon the reason for it not working. Everything is 1 click accept the presets which you have to double click, then it all worked fine.
