There is a new webmaster admin at
https://admin.ccbil.com where you can choose to log in as a client or an affiliate. In the affiliate area there is an option to view the sites that have migrated to the WMS program or to view the old affiliate admin which they now call legacy.
I spent 2 hours on the phone to ccbill support tonight to try to get all my sites migrated to the new system and we found a lot of bugs that need sorting before it is all up an running so watch this space.
