I had a pc with Windows 7 on it and downloaded and set up Windows Essentials on it. I really like the Live Writer for blogging.

I sold that PC and have another one and I have the Windows 10 on it which I Love, and I downloaded WE 2012 again and went to the Windows Live Writer but now I have no access to my blog through the Live Writer. How do I fix this? It was a Wordpress site, but I ONLY accessed it via WE LW 2012. How do I connect it back with my blog? Thanks!
