Question [Q] Owners in the US having problems? (Please Help)

So I stalked the release of this tablet and was told there was going to be a late US release. I grabbed one off of e-bay and have been extraordinarily happy with it less a few issues.
Is anyone else unable to claim the free movies (Captain Phelps, and the other 5)
Anything coming from the xperia lounge is telling me "The voucher is currently not available, please try again later" is anyone else having the issue or are these benefits just region locked?
I don't have a warranty due to the fact that the US won't honor a warranty from overseas so can anyone tell me what I'll be losing from root.

Sorry if these things have already been asked, I've searched through the forums but may have missed it.
