Hi,
I downloaded the Destiny demo and loved it, so I went to look at the Destiny Collection on the Playstation Store. However, the PS Store says I already own Destiny, even when I delete the demo. I've never played Destiny before this and definitely haven't already bought the game.
Also, when that didn't work, I tried to buy the Taken King Legendary Edition through the demo but I got a Query Failed pop up, saying the PS Store couldn't be accessed. I can buy it on the PS Store but I don't want to mess anything up more than it already is.
Is there a way to fix either issue, because I would really love to buy the full game? (ideally the Collection)
You should delete the demo to install the full game anyway, so try uninstalling the demo and then proceeding with the purchase of Destiny the Collection.
If the Collection still says you cannot purchase it, your best bet is to contact Sony - since they run be PSN store and your account, they would have to fix the block on their end.
