Dear Aerosoft Support,
I am experiencing an activation issue with the following products purchased through Aerosoft and installed via Aerosoft One:
FlightSim Studio 727-200 Passenger
FlightSim Studio Super 27 Expansion Pack
Both products were bought through Aerosoft One about already a year ago and had been working perfectly fine ever since.
After updating MSFS 2024 from SU4 to SU5, the Aircraft EFB requested license activation again. I entered the activation codes exactly as shown in Aerosoft One, but both activations fail with the error message:
"Access Denied"
I have already verified the activation codes multiple times and copied them directly from Aerosoft One.
I also already attempted the following troubleshooting steps without success:
Reinstallation of both products via Aerosoft One
Clearing the MSFS WASM cache
I already opened a ticket in Aerosoft One on Sunday, May 10th, but I have not received any response so far.
Please let me know how I should proceed from here.
I have the following information and documents available in case they are needed:
Aerosoft invoices for both purchases
Screenshots from Aerosoft One showing the activation codes for both products
Screenshots of the EFB activation error for both products
Aerosoft ticket number for my support request
Best regards,
Chris
