Thank you for your help Dave adn Colin. The issue was resolved. At some point my Sketchup Pro 2018 license was updated to 2019 and I was unaware, so I kept trying the new Licensing info on Sketchup Pro 2018 instead of 2019… After reading many posts on the Forum, I found someone experiencing the same issue and this was their fix as well. All working as it should once I installed 2019. Still not sure how the update to 2019 happened, and my Sketchup Account Manager shows only the Free version of Sketchup under my products. Either way we are back to work now. Thank you again.
