When i try to login, then it says its failed, but im saying the right password and the right ID, but still i cant login?  some one there now why?

if it says  it is not invalid version. i think you should unstall the program, not deleting the client, delete the profile in which the program install  and then reinstall it.   it will update automatically after you rerun the game.

I think he's not entering his beta account is why he can't log in, but we can't really help him if he doesn't give us more detail.
