We have closed the international edition transfer months ago, not sure if you have applied it.
You can check it by submit a ticket via https://ordersystem.mythofempires.com/?lang=EN-US and our customer service team will help you
I think maybe the old account was inactive for a long time so it was easily locked. You should probably recreate https://geometry-lite.co the account from scratch and play again.
i brought this to suuport when they where removed form steam but due to working away a lot i missed the transfer window ( sorry i have to work)
the respose is you need to buy the game again and the tranfer window in closed and it may not open again in the furture pay attention to annocuments ) again sorry i wrk away )
