I get invalid code error when trying to register my Mac preorder.

I ordered the Mac version from the Square Enix store and it keeps saying my code is invalid. Has anyone been able to register their Mac version successfully?

I thought Macs didn't get early access and had to wait for launch on 23rd?

I knew there was no early access.. turns out the Mac code is just for preorder items, and that it won't be active until the 23rd. I was trying to set up my service accounts ahead of time, but I suppose I'll have to work through the flood of day one buyers as well.
