How to find license for SketchUp Pro

I have installed SketchUp Pro. I used it for about an hour and then shut it down. I also shut down Windows 10 and went back in. I opened up SketchUp to use it again and came up with the following aggravation.

This device is not authorized. Please sign out and sign back in to continue or enter a classic license. Use SketchUp to manage a classic license.
Nothing I’m trying seems to help. I don’t even know what the LC looks like. The only thing they can find that looks somewhat like an LC is SKP-PRO??/?.

I did have the trial installed prior to purchasing and installing SketchUp Pro. Before I installed the purchased SketchUp Pro I uninstalled the trial.

Have you tried this? Try it here:Trimble Identity

I will give it a try but first I have to find the license number. The only thing I found so far is something that looks similar to this:
SKP-PRO???.
Which I doubt is the actual license number. But one never knows.

You don’t need a license number, the license is tied to your login, so sign in with the email address and password that you used to purchase the license.

Thanks
