If you are still having this problem, the first thing to check is that your system is fully updated, especially the graphics card. Outdated graphics drivers are the most common cause of crashes and issues with advanced animation software like CrazyTalk 8.
If after running Windows Update and updating your graphics drivers you still have problems, please contact our Technical Support department using the link below. They will be able to advise you further. Thanks.
