Updating existing stream
 

I am currently moving my station stream from Radionomy to a new host which is a Shoutcast v2 provider, I currently have a listing in the Shoutcast directory of my Radionomy based station which I would like to update the current listing to my new stream which I need an Authhash to do so, my problem is the station was automatically listed by Radionomy since they own Shoutcast and I don't know what the Authhash is, can anyone figure out a way for me to find out the authhash of my original station so that I can just update that listing instead of resubmitting under a different name?
