It claims it’s nulled but im not 100% sure.(could someone that knows more check this?)

So here it is for everyone.. just follow the install guide.
- the install guide in this will explain how to install the other versions.
- thumbnails, game packs and the gamesql from other 3.x versions of GSS will work.(includes NO GAMES OR THUMBS)
- if you get an SQL error cat=\’Action\’ error, simply check your php.ini and turn off magic quotes.
