Sharing Libraries...won't hold the save?

[gizbug]

I am putting a check next to music and video in my Homegroup, and hit save. When I come back, only one that has a check is printer. It won't seem to save my music and video. I remove the printer check, save. Come back, printer has a check. Any ideas?

Also get "windows can not setup a homegroup for this computer"
Heard people with this issue, say its router related. My router is for my ATT Uverse.

If your router doesn't support IPV6 functionality then the homegroups won't work although you will still be able to share files using the Home or Work sharing profiles which is safer than using the public sharing profile.
