I'm new to Unity (2017.2.0f1) & Vuforia, got the basics working using a Mac & iPad2017, but I can't quite get a custom target working. When I import the Unity Package downloaded from Target Manager, I get the following error:
XmlException: invalid data.
System.Xml.XmlStreamReader.Read (System.Char dest_buffer, Int32 index, Int32 count)
Mono.Xml2.XmlTextReader.ReadTextReader (Int32 remained)
Vuforia.EditorClasses.ConfigParser.fileToStruct (System.String configXMLPath, Vuforia.EditorClasses.AuthoringInfoXmlProvider authoringInfoXmlProvider, Vuforia.EditorClasses.ConfigData configData)
Vuforia.EditorClasses.ConfigDataManager.ReadConfigData (System.String dataSetFilePath)
UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at /Users/builduser/buildslave/unity/build/Editor/Mono/EditorApplication.cs:127)
When I click "Open Vuforia Configuration", there are no choices under datasets. I've also tried clicking add database, downloading the Package then importing into Unity, but that gives me the same error.
I've seen a few posts with the same XmlException error, but I can't get their solutions (editing the XML document settings in Notepad++ or Text Wrangler) to work. None of those posts really had a definitive answer to explain what's going on. Thanks for the help!
