Getting message saying my cs6 isn't authentic

[#1]

I own CS6 and have digital subscription via my account on Adobe.com. Over the past couple weeks I get a pop-up saying that my software isn't legit. I called the number listed and a person said she needed to transfer me to tech support where they will uninstall my version and help me download the newest version. I don't want the newest version...I want to keep using the version I bought years ago.
