I want to use an older version of Photoshop. I have the official copy, activation key etc. However, every time I start Photoshop it asks for registration. I tried internet and phone registration but they seem not to work. Please advise how to register the product. It is Adobe Photoshop CS version 8 for Windows.
The CS/CS2 activation servers have been retired. Download CS2 and use the new serial number given to the right of the download link.
