The program 'freezes', stops or suddenly hesitates without an error message.


When the simulation and/or computer stops responding suddenly, this is known as a lockup or freeze.  There are several possible causes and solutions to this difficulty.

Video Drivers:

If this occurs while in the simulation, it generally indicates a problem with the video card drivers. We strongly suggest that you update the video drivers and then fly once again to determine if the problem has been resolved. 

Sound Drivers:

The difficulty may also be caused by sound card drivers. Update your sound card drivers. Once the update has been completed test the software to see if the problem has been resolved. If not, try turning Off the sounds in your simulation.

Additionally, you can test the computer's basic sound compatibility to ensure that it is functioning properly.

If this difficulty occurs when starting the program, make sure that you are running the latest version of the software. If so, make sure that your video and sound card drivers are updated.

These difficulties might also be attributed to other programs running in the background. These applications may be using system resources that are necessary to run your simulation. Use CTRL-ALT-DELETE to ensure that nothing else is running in the background. The process for turning Off additional applications varies by operating system. For information on how to do so, we suggest that you consult the owner's manual for your particular operating system.

Still doesn't work?

If the program still exhibits difficulties when starting, and you have utilized our suggestions above, please contact us for further information and assistance.
