I have Photoshop CS2 and want to upgrade to CS3. I noticed in the upgrade requirements that the serial number for my CS2 is required and that I need to connect to the internet. I cannot locate my CS2 box (I know--there's no excuse for losing it). Does anyone know if there is a way to get the serial number from my program on the computer? Also, does anyone know what is required when I connect to the Internet? I am not the most knowledgeable about computers and will appreciate any guidance. Thanks.
