"there's a problem communicating with the itunes store"

Suddenly, my 3rd Gen ATV shows "there's a problem communicating with the itunes store" when I try to watch a purchased tv show or movie. My purchased content is all there but I can't watch it. I'm signed in and did a network test with no issues.

I've tried:

1) restarting the ATV

2) restarting my router

3) restarting my Ethernet switch

4) restarting my modem

5) factory reset my ATV

6) sign out & in iTunes store.

Nothing has worked. Please help. The ATV functioned perfectly a few days ago. Then, I bought The Office & DC comic movies and no it no longer works. Could it be the DC movies? (Haha)
