Hey guys, can someone please offer some sage advice. I have physical copies of ARR and HW but I have added the funds to my Steam account to purchase Stormblood. I know that if you purchased the original games via Steam you can only upgrade via Steam but what about if you had physical originally? I can't seem to find an answer online, only for the other way around.

I'm concerned because I've got a message on the Steam checkout telling me that the transaction failed because I need A Realm Reborn. Is this because I NEED a Realm Reborn Steam version or is it just assming I don't have the game in some form?

Does anyone else have experience of this or can point me to an answer?

Any advice would be greatly appreciated
