Why isn't the frame animation not changing its animation? I've just rendered an animation about a intro, and it seems likes it's on the same thing and it Isn't changing. I'm on frame 21 it just shows the same animation over and over again. Here's is a screenshot of what is repeatably animated.

Not sure if it answers "same animation over and over again", but your end frame is set to "5" in the image, so it would stop there.
