Why shape key animation is not imported in new version

I have a shape Key animation with some object. ( version 249b )
When I append this object into Blender.262, I get the object but shape key not animating?
For testing the blend file is attached.

The shape key animates for me on opening your file in 2.62 and pressing Alt+A

Note: to actually see the shapekey value change in real time you need to go to the timeline / playback menu and enable ‘Property Editor’

I know that. When I open the file, it works, but I have lots of other files for other work. Its not working when I append the object.
