I mistakenly purchased the upgrade prior to the actual program due to daily prompts that the upgrade was on sale.
I tried submitting a help request twice today with a .jpg screenshot of my version and s/n info and an error occurred - support request could not be saved.
Maybe the activation was invalid because of the reverse order of purchase.
I downloaded & reinstalled today because I have a new PC. What I installed is
23.0.1.318 (UDP3)
UG Code 8488 KA1.
Thank you
