Using OS 10.9.2 on an Intel Mac, my CS3 Photoshop says . licensing for this product has stopped working.' I've reinstalled and attempted to use the fix in the Adobe website. However the fix will not work on an Intel Mac only a G5.
For Intel Macs running 10.7 and above, there is a python script that you copy and paste into Terminal. Have you tried it?
