It's 2020 and CS3 and earlier are officially dead now. The activation servers are gone. Adobe ended the replacement program by removing links to activation-free installers and serial numbers. It is no longer possible to re-install CS3.
CS 4 - 6 are on life support. Going forward, if you want Adobe product support, you really need modern software or a paid Creative Cloud Plan.
I want to make sure I understood this correctly, the program that I've paid for on the basis of a lifetime use, is no longer acknowledged by Adobe? is there a refund?is there a solution for the customer?
You definitely can't expect me to put more money into a new product to also "have the servers retired"
I'm sorry to say there is no such such thing as a "forever license" and never was. At most you had a limited, non-exclusive license to use Adobe-owned software for as long as they could make it available.
Product support for CS3 ended in 2010. Had you upgraded to CS6 when you had the chance, you might still have software you can use. But that opportunity ended several years ago when Adobe pulled Creative Suite off the shelves.
Option #1: buy Adobe Photoshop Elements 2021 (no subscription required).
Option #2: buy a Creative Cloud subscription plan.
Option #3: buy software from a competing company.
Option #4: find other interests.
Whichever you decide, best of luck to you.
