I have PSXT running, Real Traffic and FSLTL. I cannot inject flight movements on an historic date and time into MSFS 2020. Every time both loads it just shows live flight movements. I have paid for the 1 month professional edition and I only want to go back a week and fly JFK to Manchester UK. How do I inject flight movements on a historic date and time? Do I need FSLTL running at the same time or is that the problem, I should not have it running?Thank you everyone for your advice.
