After hunting around for information on this error:
I found this http://groups-beta.google.com/group/...fba6e5334aab97
which indicates it's after the file control.xml
So I've been able to add two different .au sources correctly after checking a few servers for this file and making a note of the path to it.
eg (entered exactly as shown)
Directory on Server:
The control.xml file existed in both servers.
Why this information isn't more easily available I don't know.
