I run Starry Night Pro Plus on my 2007 iMac, under Yosemite (10.10.3). Starry Night updated itself to version 7.2.0 today, but then crashed on launch every time I tried. I was able to retrieve version 7.1.1 from my Trash and that still works, fortunately. I thought you'd like to know. Do you have any advice?
All the best
