Hi Bignewy and thanks for the suggestion!
I did buy these through steam before I switched to standalone. I went to the account page, and sure enough hitting import found licenses for the individual fc3 aircraft. Now I no longer get the authorization warning on login, but I still can't use the FC3 planes. The new launcher --> file --> available still shows a red 5 but doesn't have anything on the screen. When I launch the game, the FC3 icon indicates that I don't have it, and the module manager suggests I need to download it. Allowing it to download through the module manager just results in the same situation. I tried running a clean and a repair, but that didn't solve it either. Hope that information helps in any small way!
Thanks! Appreciate you and NineLine trying your best, I would NOT want to be either of you guys right before or after any major patch hahanullnull
