Wow... I dunno if it works or not, but that launcher is the first thing I've seen in about 10 years that makes me think they've hired a new programmer. It looks modern! I mean if that was the first thing I saw when loading EQ I'd think it was a new game.
Go into your Everquest folder, look for the file called "Launcher" (the icon is a blue play arrow), delete that file, now look for the Everquest.exe file, run it. This SHOULD download the correct launcher.
