Trying to play on another computer, won't let me?

[Zenaku]

Can log into his account on my PC just fine.

Now that odd o.O wonder how that works then. Seeing how me and my gf both have PC account from playing ffxiv from release date of 2010. Just sure how i can help i was pretty sure he would get a wasn't "unlocked" for this version also.

I guess PC version can play on Stream client but a steam client can't work with a PC one is what i'm thinking. I guess we wait for someone else to post who may know more.
