After getting replacement computer using Windows 10, I installed my copy of FSX Deluxe with Acceleration. I’ve been running this with 3 monitors, Saitek Yoke, Throttle, and three panels for several years on Windows 7. I never got the registration screen after installation and now when I try to fly it quits saying my 30 minutes is up. I’m using this with Windows 7 compatibility mode. PLEASE HELP
