How to activate my old sketchup pro classic perpetual license on my new computer

I got a new computer and I’m trying to download and activate my old sketch up pro license. I downloaded the 2017 version and my old SA-xxxxx license and authorization code didn’t work. I then downloaded the 2018 version and used the same license with the TA-xxxxxx number and same authorization code as It is the only one I have. That didn’t work either.
what do I have to do to have sketchup accept my license?

Both of your licenses should work. When you activate 2018 the 2017 won’t activate anymore, so make sure to activate 2017 first, if you want to have both versions.

There is a good chance that you are using the wrong authorization code. I will send a message to you with both sets of numbers.
