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

[Oce]

I tried searching for an answer to this on google and by browsing the forums, so I'm sorry if this has a simple answer already!

I own the game for PC (bought through steam due to convenience, which I now regret immensely because of all the stuff going on with steam versions), and my husband owns the game for PS4 and PC (non-steam version). Last night, I tried to play the game on his laptop since I was just going to be doing a bit of grinding, but it wouldn't let me connect and stated my account wasn't "unlocked" for this version. I wasn't aware that the game would lock me to my own PC, and frankly that seems very strange?

Is there a way around this?

Is there a way I can purchase the non-steam version and link it to my account if this is going to be an issue?

EDIT: I seem to have figured it out, looks like for some reason my client was selecting an inactive FFXIV service account instead of my actual one, switching data centers and reselecting my proper one has done the trick. UwU
