Has the process changed for moving Zend ID? (Freepbx 13.0.49)

I checked the article

http://wiki.freepbx.org/display/FPG/How+to+Remove+a+Deployment+ID-License+File+from+your+PBX

and clicking the De-Activate button doesn’t seem to do anything since when I log into the Schmooze portal it still shows a Zend ID. Clicking it in the portal does release it but I am unable to start the registration process over in the GUI. I deleted the two files in /etc/schmooze (license-xxxxx.zl and pbxid) but the sys-admin page keeps saying that it’s registered. Clicking “Update Registration” just brings back the old zend ID.
