Getting similar error to
I get this error the moment I click 'Open Vuforia configuration' on my ARCamera.
The complete error is
XmlException: invalid data.
System.Xml.XmlStreamReader.Read (System.Char dest_buffer, Int32 index, Int32 count)
Mono.Xml2.XmlTextReader.ReadTextReader (Int32 remained)
I tried resaving the XML data as ANSI but made no difference.
This is a showstopper' for me and will prevent me from considering Vuforia as a viable option unless I can find a solution in the next day or so.
Happens in both OSX and Windows versions of the Unity Pro editor.
