MacLink plus and Mountain lion no longer compatible? How to read WP files?

I just upgraded to Mountain Lion and MacLink Plus won't work. When I click on MacLink Plus, I get a message saying PowerPC applications no longer supported. I went to the Dataviz site, but MacLink is not even listed as one of their products. I have hundreds of Word Perfect files from years of using a PC. I was just translating them into readable form as I needed them using MacLink Plus. I will be lost without it. Is there another product out there that can do this? Why is MacLink no longer being supported? Any help will be greatly appreciated. I was using Snow Leopard and that was fine, but I wanted to be able to use ICloud to keep all my devices up to date.
