I’m sure this has been answered a bajillion times back when it was released 256 days ago, but I’m a little slow. Plus I don’t feel like searching so I’ll go straight to where I know somebody knows what I’m asking, ya know? Anyways, what all do I need to upgrade from Flash 8 Pro to Flash CS3? I assume I’ll need my old serial number but is there anything else?
