Yeah I understand what you are saying now. It is pretty similar to how Quickbooks works from when I helped someone the other day with it. However, I do understand the situation, but it may be best for you read some or all of the FAQ's, End User License Agreement, visit the activation center, adobe announce upgrade policy, installation on multiple machines, the entire "Installing Software" section and scroll up to the "Software Trials" section of this link...
Adobe SupportHere is a link for their
Customer Support. You may want to contact them and see what they say, or what they can do for you.
As you mentioned, the PS3 seems to be no longer available on their site, yet the upgrade requires it's previous installation. They may have to mail you a cd or link you to somewhere we don't know about to download the older version.
That above link that I titled Adobe Support should help with some of the questions and their customer support should be able to get something done for you especially since you are a current customer.
I guess in short, if the update/upgrade requires a previous version then you have to somehow get that previous version. Or, have them provide you will a complete install of PS4 that will let you use your old license number, or they may just issue you a new license number at no charge because of your unique situation.
I would think they would be willing to work with you, but you never know.
Hope that helps!
