While trying to add my Xbox 360 to Windows Media Center with Windows Extender I keep receiving the following error: "Configuration Error. An error occured while configuring Etender settings. Restart your Extender and computer and try setup again."
I have tried removing the Media Center Extender certficate, and the Network List Service doesn't need to be restarted. I have deleted any computers that were previously linked with my Xbox (there weren't any), and I have tried deleting the Xbox Live Dashboard from my gamer profile in My Xbox.
Windows Event Viewer has given me the following error messages:
Windows Media Center Extender setup failed with the following error code: -205.
Windows Media Center Extender setup cannot create account Mcx1 for device 'uuid:10000000-0000-0000-0200-00125AAA2C01'. Error code: 0x8007012b.
