Strange, while my bba allowed me to auto connect to quake servers, it the offered pso pal v2 disc from here told me I needed to register with a dreamkey?
I don't usually try to download backups unless I already have a hardcopy of the game, but would this be appropriate?

The original servers for Quake 3 are still up so you can still easily get to them. But these are private PSO server in which you either need the autoconnect disc for this server or you need to download some gamesaves etc. which is a little harder.
