Hi,
I do have a similar (or same) issue. When I try to log onto Kindle-For-PC with my correct email and password I get following error message: "Failed to connect with http status code 0"
I tried your fix, but the link
https://firs-ta-g7g.amazon.com seems broken.
Anywhere else I can try get the SSL certificate?
I am running Windows 7. My second computer running the same system connects fine.
