Hello, I am also one of the many. I had a license with my employer, of which I am no longer employed. Attempted to purchase a new license to use on my MacBook, which had the software still installed from my previous employer, and apparently I purchased an upgrade key instead of a full license. Can you please refund me and send me to where/how to purchase a new license, thank you

Hi,
I just went to open my old version, and it said upgrade available. Clicked the link and paid for the upgrade, but now it says whats the previous licence. No ideas, too long ago.... Any advice/help much appreciated, as a retired person, every cent now counts...
