Hello Krypton Radio,
By "added a new stream", I assume you are talking about a new mount-point, if that is the case, this could be related to the recently added bit-rate enforcement to Icecast stations, or it could be simply that you are not setting your tune-in links and player correctly.
If you would care to open a new ticket to our support department, with the login details of the affected station, we'll be happy to verify the problem and open a bug report for you if needed be.
