Don't use it for paid work. Adobe is shutting down the auth servers for CS2, but needed a way for current CS2 users to keep using/installing the program. So they released this version that doesn't connect to the auth server and just takes a generic key. TECHNICALLY it is only for people that have a paid license for CS2, but for whatever reason its completely open to the public to grab it.
But if you start using it for pro work and you get software audited, you're kinda boned.
