Need Download of Elements 2021 for Mac since I have no cd drive now

When I bought a new computer 2 -1/2 years ago, I purchased Photoshop Elements 2021. It came with a cd for Windows and also 1 for Mac.  

About 6 weeks ago I purchased a Mac Mini with no CD/DVD Drive so I came to Adobe to get a download of PE 2021.  They downloaded 2022.  Today I decided to try it out.  So of course I had to provide a serial number, which I did.  Well, the number I have is outdated and Adobe wants me to purchase a NEW PRODUCT.  The 2021 didn't get  a lot of use and now they want me to buy another. NO WAY!

I really did not like 2021 all that much anyway. I guess I will have to use my old laptop with PE 7.
This is so wrong! 

I always loved working in Elements and have made so many cards. I'll have to keep an older version of Elements just so I can print them.  Elements 2021 on my Windows 10 computer  constantly freezes up (as does Word and many other things) and I must use Task Manager to close it.  The cards I tried to print did not print correctly.  How much is Elements and how much is my computer and/or Windows, I do not know.  The computer crashed at 4 MONTHS old and I had to install a new Windows 10 and it's been downhill from there.

Excuse me for venting. This is really close to the last straw!!

Is there any way I can just get a download of Elements 21 to my Mac computer?
