Google is your friend.
OK -- here's one exact example: Bought PSE-12 (Adobe/photo = $60) and when I installed it and registered the ID number, it popped a window "This ID number is invalid" ... So, where do I get a valid ID number on Google.
Been screwing around with on-hold, no call back, call back and no valid number, asking the same questions over again -- then, OH, I'll get it and call you back. And no call back, and another on-hold. You keep thinking this time, this one will fix it - but it's a continuous failure ... and you finally give up. Yeah, I can call the CC company and refund ... that's NOT the issue. I want the program I bought to function - and it won't.
And CS simply never does anything but run in circles. So, what is the option? We'd LIKE the program, we want to use it ... so, what do we do, stop buying programs, stop using our computers. It's not that simple.
And there is no way to hold these companies accountable for selling a "number of bad copies" of the product ... and the fix they offer, ignore dissatisfied customers and they will go away and leave us with our profits.
The generations arriving now - they have grown up in a throw-away society, and it's "Just normal, dad" ... toss it and buy another one ... "That's the advice."
