I've been trying to play on my Windows 10 PC, but the game reports that it cannot login to XBox live. I have signed-in to the Xbox app on the PC, but the game still does not sign-in to grant access to any of my purchased tables.

I've had Pinball FX2 on several platforms: Xbox 360, Windows 8 upgraded to Windows 10, and PS4. As I recall, tables purchased on Xbox 360 did not carry-over to Windows 8, so I suspect that I may have more than one account on the Zen Studios servers...

What steps can I take to get the game to recognize my Xbox sign-in? Is there a way to merge any accounts such that I have access to all purchased tables?
