To answer a few questions you can't use this on retail or play with people who have gotten into beta.. When your accepted into beta your given a beta key and after its applied you "character copy" one of your characters to the beta realms (which is only possible after your account is flagged as a beta tester). Than after that you make a temporary account that is used for to login to the beta server making it impossible to use your retail account to get into beta. Than your given a download link for the blizzard downloader thats set to download these same beta files. Basically for the non betas here all you can do with this is install WotLK Beta so that you can either 1. Use the files to update your PServer to WotLK beta or 2. Use the game client to connect to someone elses WotLK PServer. I'm only here because blizzard only gave me one download option which was the slow ass blizzard downloader but maybe ill use this to update my PServer as well.
