Paid for beta access on 2 accounts, now can't invite my son

I paid for beta on 2 accounts so I could play with my son. After exiting the game to allow new graphics settings to take effect, I can no longer invite my son. My son can no longer invite me.

This completely defeats the purpose of the purchase and wastes my money.

Please help.
