Duplicate Steam Key

So i received my official download information, but when i try to use my key it says it is a duplicate?
So i can’t access the beta. Anyone run into a similar issue?
It says its already been activated by a different steam account 0_0

Edit: I suppose many of us are dealing with this; 343 is aware and working on it tho. Check unysheks twitter
