I coughed up £60 for the battlefield 4 digital deluxe edition so i got the china rising expansion pack off the bat and it works fine, but later in the year when i installed premium and all it's dlc(Second Assault, Naval Strike and Dragon's Teeth) i found i couldn't play on any of the premium expansions and was getting the error message 'Requires additional expansion pack, Battlefield 4-X, you need to download and install this expansion' i tried changing the registry to Xpack1, and got nothing also Xpack0 for the same result im using google chrome and have on several occasions repaired my Battlefield 4 and all the expansions but all to no avail EA please help i've spent near enough £100 on this game and 60% of that is wasted at the moment
