In that case... here is my scenario.. tell me if you think I am okay!
I am a 1.0 CE player and I was told that I could not pre-order the game to get early access and the items because it would only let me be registered for either pre-order OR 1.0 CE.
At this point I already had my pre-order code and was trying it with everyone else, getting error 3.
So I cancelled my pre-order that I got directly from Square Enix's store, since I didn't think it was going to let me use it anyway, but then this morning I got an email from Square saying I successfully redeemed my pre-order code.
Since then I now know I can be a 1.0 CE player AND use the pre-order code.
The charge for the pre-order is on hold on my bank account but I am assuming since I cancelled the pre-order that I will be refunded the money. When I launch the game, it gives me the message, Please wait until the start of the early access period or official launch to access the game. like it is supposed to..
But I worry that it will know I cancelled and didn't pay, and won't let me in...
How will it know? What if I decided that I didn't want early access and gave my code to you or someone who didn't pre-order? Anyway, you're fine. It doesn't matter. I have no way to back that up or anything but why waste any effort at all to find people who have stuff for the pre-order that didn't really pre-order or canceled the pre-order. The only thing that COULD have happened was, if you cancel the pre-order the code is deactivated but even that would take too much effort.
Anyway, I just gave a code to someone from an item I canceled and it worked fine. Don't sweat it and enjoy your items :p
