Have activation code for Premiere elements 2020, but need to use 2019 and code will not work [macOS]
On MacOS (10.12.4) - I inadvertently got premiere elements 2020 and my system will only support 2019. 2019 will not accept my activation code and I am terrified to upgrade to high sierra in fear of having to upgrade a lot of other software. I cannot seem to find a location to ask for help with this and wondered if anyone could point me in the right direction.
