Hi, I just switched from an iMac to a Macbook. Got the Macbook for college stuff and I'll be selling my iMac shortly. I transferred everything over to my Macbook via an external hard drive, following the instructions on screen. It transferred everything successfully; couldn't be happier. So I pulled up Photoshop CS3 on my new Macbook. The error message displayed is The licensing has stopped working, with no error code provided. Weird thing is, the products still worked on my iMac. So, I proceeded with these steps: Deactivated my licensing on my iMac Uninstalled Adobe CS3 on my iMac Restarted my Macbook, same error Used Adobe's license repair tool and removed the licensing registry from my iMac Restarted my Macbook, tried again, same error Uninstalled CS3 from my Macbook Reinstalled CS3 on my Macbook Restarted my Macbook, tried again, same error Used the license repair tool on my Macbook, removed the licensing registry from my Macbook Uninstalled CS3 from my Macbook, re-installed everything Restarted my Macbook, tried again, same error I am absolutely out of ideas as to what to do. Please note that this was a computer TRANSFER, so I don't suspect is has anything to do with the weird CS3 network errors some people have had in the past. Both my iMac and Macbook have Snow Leopard on them. Since I find that most technical support is not helpful, before I call them up, I thought I would ask the community about this. Any ideas? Thanks in advanced.
