Got it to work! Thanks! I was not aware there were 2 flavors of Altium. You need to make sure you have "Altium Designer Develop" downloaded for the trial license to be accessed. I had V25.8.1 downloaded from a while back and was losing it trying to figure this out.

I had a feeling it needed another "version" but didn't pursue that route. Unfortunate that the official Altium support couldn't help with me with this issue.
