Yes it was. This was posted for one of my officers (roommate w/e) that is running vista and couldn't get the mod working. Long story short, the actual world of warcraft launcher.exe was in a different location than all his other addons. For some reason, when extracted the GRSS mod wasn't "copying" over to the REAL location of the addons. (love vista btw, glad I didn't conform to that one...)
It was in some folder like c
users/public/games/worldofwarcraft... etc.
Took a little convincing to let me get on his comp to find it, but tis all better now.
Thanks for the amazingly fast response time by the way, I was just getting back on to say "nm, I figured it out."
Cheers!
