Aragorn, if you are in-game => what does the BF icon say? And those 6 keys => are they all from act 2? Or are you playing an earlier version, where you could keep old BF keys from earlier acts?
If you just drag and drop the battlefield keys in to your inventory, they will not register. Try to drop the 6 keys to the ground, and then left-click them. A messagewindow will then tell you that the key is activated. Hope this helps
