Unable to sign in to Navdata Center

I have been trying everything to be able to Sign In to the Navdata Center. I have rebooted computer, turned off firewalls, reloaded the program and it still will not open. It was working fine and I don’t have a clue what changed. I currently have my community and Official folders on an external drive. Have tried putting Navdata Center on same drive and it doesn’t work. What is the best location and path for the Navdata folder? I would like to put it on the external drive to save space on my C: since it’s not very large. This is with the FS2020 sim.

Finally got it working. Near as I can tell the problem revolved around my default browser. Thought I had experiment with both Edge and Chrome but apparently was doing something wrong.

Thanks for the positive update …

Happy flying
