I am afraid that if you have changed the password, there is no way to recover said password all you can do is reset the hub back to the factory setting, to do this with the power on, press and hold the reset button for a period of 60 secs, do not turn off the hub, wait approx 5 mins until the light stablise and then you can use the default password as listed on the sticker in the base of the hub.
