starting over

[She-Wolf]

Hello y'all, I have not played SH3 for, maybe a couple of years now, moved on to SH4, and once I got comfy with the new way of doing things, and mastered (to a point) the manual targetting, I pootled around in that quite happily for a while, and also, because I have it sitting here, occasionally I dip me toes into SH5 - you gotta love the graphics! - and so these two, and a few other games have kept me sweet and occupied... but, but.. I still miss the FUN I had in SH3, and I want to give it another go.
Of course it will have to be the GWX megamod, and I thought I had squirrelled all the necessary files away, but can't locate them now.
All I can find is a nocd fix from 2005.
I think I recall something called emea with a green icon, and something about an update which has to go on before something else - but the details elude me, and if I can't recall the names I can't search for them. Can you help please? I am now on Windows 7 62 bit and am hoping that will not be a problem...
