Not sure why this started happening but when clients try to add their mp3 key they get

Fatal error: Call to a member function to_xml() on a non-object in /usr/local/centovacast/system/class_XML.php on line 741

Somehow the client deleted the only mountpoint they were allowed, it would not allow the mountpoint to be edited, highlighting the /stream did nothing -   I receated the account and it's fine now
