I am including two images of what happens when I triy to apply movement or animation to titles. It has just happened all of a sudden. It does no even allow me to see the preview.
I was thinking of uninstalling program and reinstalling it again, but before that I would appreciate if someone could give me a reason why it is happening ( so if I am doing something wrong I can correct it) and also a fix.
Thanks in advance for your help
