Dragon Age 2 Ser Isaac's Armor Not Unlocking

@EA_ShepardAlright, I guess I'll give the password reset a try and see if that does anything. I assume that the aforementioned replay option in the Keep is "Replay Startup"?

As for repairing/reinstalling, I'm playing on Xbox, so there's not much I can do in terms of repairing the game, but I'll try doing a full reinstall. Maybe I'll try buying another DLC to see if that helps refresh things.

Sucks that this can't be fixed on the backend ☹️

Edit: Could decoupling my Xbox account from my EA account and then recoupling it help in any way?

@EA_ShepardAlright, I just reset my password, went into the Keep and replayed the startup, uninstalled and reinstalled the game, and launched it to see if anything changed. Nothing did.

I even tried unlocking more items (I think Air of Confidence and the Arlathan Focusing Crystal), but nothing changed (I admittedly only did this after I launched the game post-reinstall). I still only have access to the same selection of items, that being the following:
- Boots of the Frozen Wastes
- The Far Cliffs of Kirkwall
- Lothering's Lament
- Of Things Not Lost
- Fadeshear
- The Lion of Orlais
- Staff of Parthalan
- Blood Dragon Armor

The only other things I can think of doing are loading the game on my Xbox 360 instead of my Xbox One, decoupling and then recoupling my accounts, and/or going through the steps you recommended all over again.

@EA_Shepard Alright, I just tried booting the game up on my 360 itself to see if that would change anything. It didn't. I additionally will not be trying the "decoupling and recoupling" idea because I remembered that that latter part is not a thing that you can do. So I'm at a loss as to how to proceed.

There has to be a way to fix this issue, but it seems like nothing you've suggested has worked. I don't want to be locked off from this content permanently on my preferred platform!

Edit: So I just tried unlocking (almost) every reward item for DA2 that isn't unlocked via an achievement in one of the DLCs, and while I was able to unlock Hindsight and Dura's Blue Flame, nothing else appeared.

I don't understand why this is happening. Why are only some items unlocking while so many others are just not? Why has the system denied me access to Hayder's Razor and Ser Isaac's Armor? It is in particular baffling to me that I cannot access Hayder's Razor, since I HAVE completed the demo. Multiple times, in fact. And on both Xbox 360 and PC!
