Ok, i know most quakers have the original game, or had it -
let's face it, it's a really old game in todays standards.

Once upon a time there was a guy named Rudz, he bought quake3 and was happy .
He quickly made a backup so nothing would happend to the precious game (which is legal in my country btw).

Disaster, when he discovered that he's original cd was no where to find he just installed and played from the backup using a empty key.
But when PB came he was angry, many server admins had a too tight guid relax (getting this right?) which meant that he couldnt play on those servers .

So fellos, relax/remove the guid check

Tweak other settings, make it pure - just let more play!
