WoWreader is a program that is used to provide info to alla and is not the game itself. You cannot use it unless you have the WoW client which is not available at the moment. Continue to keep an eye out for WoW's open beta and retail release. Once given the chance to play the game, you will be able to use the WoWreader program. Remember, at this moment there is no way to d/l the WoW client unless through Blizzard themselves.
Also, if you have the client but no account, then you cannot play. The only way to gain an account is through Blizzard, which they have yet to provide a method to gain one.
