product license no longer working
I have a new computer. Now Adobe CS4 programs don't work anymore
I had them installed on a MAC OS X 10.6 and now I have moved them to a MAC OS X 10.11
Do you know how I can re-activate the programs? I have a regular license, the software is genuine...

When I launch Photoshop, it says this:

It says: The license for this product is no longer working
Is there a way to solve this problem?
Thanks a lot!
