Animation will not play Recently, I've been attempting to set up an animation in Blender with the model I've made, but for whatever reason, I cannot get the program to play the animation.



I don't know why this is happening, I set up a starting and ending key frame, but when I press the button for the animation to play, nothing happens.

Because of this problem, I need help on how I can rectify it.

EDIT: After playing around with the model a little bit, I managed set at least a couple of key frames and play an animation.  However, adding key frames is still extremely screwy, with the program deleting key frames for no apparent reason.  I still don't know what I doing wrong with setting up key frames, so I've added a link to my Blend file below.
I tried your file: all fine! Unless I'm missing something, I suspect that you just press ALT-A or press "play" button and nothing happens... because you're starting at frame 60!!

try to start playing from frame 1 and it works...
