Hi..
Sorry to hear about your problems with CrazyTalk Animator.
It could possibly be a problem with DirectX9c not being installed correctly. It may be worth getting this and installing. You can find it HERE. Also make sure that you have run Windows Update to get the latest updates for your OS.
It would also be worth uninstalling CrazyTalk Animator and doing a fresh install.
If the problem still persists after that and your graphics and audio drivers are up to date then please contact Technical Support using the link below. They will be able to advise you further.
