I purchased Lightroom Classic about a year ago and everything went fine until the last several months when Adobe keeps updating my Lightroom Classic and makes it not work. I get a window saying I can start my free trial of the new version and I have to quit my version. Is there any way to stop these updates? I purchased Lightroom Classic from a third-party retailer for $30 so maybe I am getting what I paid for. If so where can I buy a legit copy of Lightroom Classic?

While I have been reading this site for several years and have loved the great images you guys have created. I have been an amateur photographer for many years but now that I am retired I have decided to get a lot more serious about it.
