help with finding the real gwx download

ok i've been gone for a month and after a defrag i was downloading sh3 when my gwx cd fell apart, the mirror just peeled off. i guess thats what they mean by discount media lol. i'm looking looking for the latest full version gwx download and the gwx team approved patches that are truely compatable. after that i can experiment with the other tweaks. can you please point the way?
