Muse Template Still Work?

Hello,

Please excuse my ignorance on this topic. I am in the process of overhauling my portfolio website and I see some beautiful Muse templates on here. I have never used Muse before but I am very active in Adobe.

I see that they discontinued Muse. Does this mean that these templates no longer work? Can I still download and use Muse if the templates do work or is there an alternate program that I would need to use? If I can still use Muse and the templates, would I be able to transfer to my hosting site (bluehost)? I just want to make sure that all this is feasible before I purchase a template.

Thank you in advance.
