Following CorelDraw Addon Code Samples but having issues

I am trying to follow along with the CorelDraw provided Addon coding examples found here. I am running CorelDraw X8

I am running into 2 major issues.

  1. They tell you that you can use your own generated GUIDs. So I tried using GUIDs made by a site they suggested. No matter what I do, buttons and menu items will NEVER show up when generated GUIDs. I even attempted to switch out the primary GUID found in the sample for one I generated online. This caused the button to disappear. It does not seem to make any sense at all why this is happening.  Any suggestions?
  2. When I do get a button to show up, even one generated 100% by the code they provide, when I click on it, I receive the error "To use extensions, you must first sign in to authenticate the product". However, my product is 100% fully authenticated and I am logged in an everything.  I tried the addon out on 2 different PCs and they both receive the same exact error.
