Upnp Pentest Toolkit Device(Error)

[steppangit]

I'm trying to run rssdp but can't seem to get my devicedescriptiondocument right.
Devices are not showing in Windows Explorer.
Upnp Pentest is able to discover the Device but is throwing errors.
RSSDPs Discovery Service is able to discover the service and retrieve the XML file.
Could that be an IIS issue or just plain xml error?
