Hey there Aerosoft Team. Last night, I experienced this issue for the first time. I was entering a flight plan from KSAN to KLAX in the CRJ 700. While entering the arrival page for KLAX, my plane locked up and I could not do anything. EFB stopped working and all switches were inop (Tried to change brightness on displays, turn on logo lights, ect, nothing worked). I then exited game and restarted at KSAN again, this time in the CRJ 550. While entering arrival data again for KLAX, my sim locked up, however this time i couldn't even free look in the cockpit and had to CTL+ALT+Delete to task manager to close game.
