Ok...so; I got a new computer, and wanted photoshop CS3 on it. after installing it, it said i need to register it by putting in a 14-digit product/serial number. I go and find the case (in my closit :-w ) and put in the serial code on the back (same one i used on previous computer) and it sais it's invalid... you can only install it on one computer :? so after a few :wall:'s and random attemps to guess it, i'm still stuck. getting a keygen might work, but it's illigal; is there a legal way around this (with-out buying a second ps)?
