I purchased a Boxee Box yesterday, hooked it up to my tv, wireless network etc and have been able to get an internet connection, stream from apps etc, but am unable to link to any information I have stored on my laptop ie I am unable to find any file sources to share

running windows 7, set up a home group per the link below

Any thoughts on what I can do to correct this issue?
