I cant access heavensward content

[Pence]

i dont think so, my friend have it on pc and ps4, and only bought the heavensward expansion for pc and he plays in his pc with no problems. Not sure if he plays it on ps4 but i saw the account myself and he have no problems.

i would understand that if that happens when entering thru pc, but my ps3 should let me play the content.

Re-read what you wrote. Your friend registered a PC version of Heavensward and can play Heavensward on a PC. He won't be able to play Heavensward on PS3/4 unless he registers codes for their individual versions, even if he has access on a PC.

The same applies for you. To play on a PC you need enter PC registration codes - PS3 registration does not transfer to PC and vice versa.
