can't log in.

[Rizzle45]

hi, i cant seem to log in for some reason. im out of town right now and just installed wow on a craptop. ive tried to reset PW but it keeps saying my email that i used to sign up isnt valid. ive tried every combination of pw that i use and put my email in with and without capitols. im kinda frustrated here so any help would be greatly appreciated. i put over 2 days game time in and i dont want it to go to waste. thanks.
