Did you do a clean install or just an upgrade?
Some say that a clean install is needed if some features don't work. I'd give that a shot.
For me, I did clean installs on both of my home laptops, and will do the same for my desktop when I get a chance (haven't turned it on in a while).
Or, you could always try a simple reboot. It takes 2 reboots to get everything working after an install in my opinion.
