Thanks for reaching out! SmartCARS Premium should save a state every 1-2 minutes and recover that when you use the restore feature. All you should need to do is load the sim using the same plane, start the engines, and click restore. Please let me know if you are able to reproduce this behavior. Unfortunately, we no longer support Windows 7 as outlined in our announcement here, so our support team will be unable to help with any issues related to your specific setup.
