Hi, great to see you back @brianbrogan1960!

Try to use Hive Keychain. It's a browser extension and It works really well. It's what most people are using these days.
As long as you have your keys you will be able to set it up in a blink of an eye.
Here's the link for the Chrome one. It's also available for Brave and Opera, depending on what you're using there.
Hope this helps and welcome back!

EDIT: Make sure you're using the private keys, and not the public ones that are displayed in your wallet, when trying to login.
