Hello.
I am located in Saint Malo Bretagne France.
I bought the 777 300ER CaptainSim via the “Market Place” of FS 2020.

Never worked properly
Don’t follow the flight plan
Does not manage programmed altitude contines to rise
The vertical stabilizer is permanently oriented to the left or right, which causes the aircraft to tilt to the right or left
FMC cannot re-enter the correct parameters of the 10° flaps imposed instead of 5 or 15
APU start and APU Gen does not need to start the engines before the push.
Can you help me and advise me?
In advance thank you for your help.
Cordially
