Solidworks not available on 3d experience?

I've since watched multiple videos and scrubbed through the 3d experience but can't find how to use solidworks. I previously had the student version of solidworks. When I found the "Solidworks plug in" on this site, I clicked it. It then opened my outdated student version and said I couldn't access solidworks. So I thought to uninstall and try again. Clicking again it just says now "No compatinle solidworks version found". I'm unbelievably confused and just want to design my prop and be done with this. Can anyone help please?
