Graphics Suite 5 and Windows 10

I have just loaded Windows 10 onto one of my computers and everything seems to work - except for Photopaint X5. I seldom use Coreldraw these days so haven't tested it yet and could manage without it. I could upgrade to Graphics Suit X7 - assuming that it will be made Win 10 compatible soon but this would cost over £200. I could save huge amounts of money by switching to Paint Shop Pro.

Is Paintshop Pro Win 10 compatible? How much functionality would I lose compared to Photopaint  and how big is the learning curve between it and Photopaint? Should I move to Lightroom !!!!

Thanks
