I'm trying to pre-order [b]Destiny: Rise of Iron[/b] but cannot. Error: "You are not able to purchase this product for the following reason (s): You have not purchased Destiny: The Taken King." I downloaded a copy of Destiny originally through the PS Store, then bought a disc for The Taken King, and want to pre-order Rise of Iron. In a household with me as the parent and several sub-accounts, [i]how does PS register a game[/i]? [i]Does it register a disc any different [/i]than a download? [i]Does it register my son's copy of the disc on his profile and not on my profile[/i]? The reason I ask the last question is that it seems that I can purchase the pre-order only through his profile. [i]Why is this so[/i]? Doesn't it make sense that all share the same games through this one PS4 console? Any leads would be appreciated.
