Re: Old school with CS2. Haven't used in a while and am unable to use the program as it says my serial number is invalid. Customer service tells me the server for CS2 has been shut down. Then they sent me here for help. Does anyone have any advice?

CS2 is very old and reached its "end of life" a while back.  So probably won't run on modern operating systems.  If you can still run it, you'll need to uninstall what you have and re-install with the download link below to activate it.
