Navigraph Center no loging

Hello, I downloaded and installed the Navigraph Installer. when I start it a window appears with a button with login. if I click on it, nothing happens even after a long wait. For MSFS2020

Hi…,

Welcome.

If you use Chrome as your default browser as a test, can you login?

Cheers
Ian

crome is my standard browser

I’ll check that again tonight though.
