[2023] ED on PC won't accept my Frontier account.

I've been playing ED on Xbox for a while now but have been wanting to make the transfer over to PC and Odessey. So when I saw it was half price on Steam I picked it up. Now when I try and log in with my already existing Frontier account it says I need to purchase or redeem it. When I instead tried to make a new Frontier account it wouldn't let me because my email was already being used for a preexisting account. I want to love this game but FDev just has to make it so hard sometimes.

P.S. I was playing on Xbox with gamepass so I'm not eligible for the free Horizons redemption.
