Uncharted PS Home game DLC code not working

[Achtung!Baby]

Has anyone else played and unlocked the free kickback dlc code? Mine is not working and says it is no longer valid.

I received an email from Kalahari with my code for the Kickback DLC the day before it was delivered. Redeemed it with no problems this morning, along with the Network Pass.

Not sure about the PS home code, but like fayainz I successfully redeemed my kickback last night.

My Kalahari dlc code worked fine, also ones friends gave me from BT pre-orders. Only the PS Home one isnt working...
