Everything is fine with the updater,it took me a while too but I figured it,all you need is to do is to torrent the client and install it,then when you download the updater DON'T put it inside the l2 folder,extract it in your new l2 e-global updater folder but not l2 where the system,systextures and so on are,otherwise like to me it will write an error and that you can't specify a path there,then specify the path to the client where all your files are(not the updater),then you won't need to update 22gb...
