I uploaded my clumsy aptempt (I'm a technologist, not an artist) from many moons ago to animate it in 3D to the XDrive account.
Sorry about the size on some of the early ones… never had a chance to compress em.

Just a tip - you know how your pieces sort of don't turn in unison, how they separate? You might want to make a dummy object and, when the pieces come together, parent all the puzzle pieces to it (and key frame it so they're not linked from the start) so you just use the dummy's gizmo (cos it looks to me like you selected them all and rotated).
Now, if that doesn't work right in whatever software you're using you can spoof it with a visibility keyframe - you need the three puzzle pieces as separate objects, then another instance of the three merged into a single object, at the exact place where your three pieces join. Then, when the three pieces arrive at the coords of the single-object logo, you just make the three pieces invisible, and the one object visible (same keyframe). Then rotate the one object. Course visibilty keys are a pain in the ass because they never want to work right.
All three parts are part of a group, and the group is being rotated on the z-axis… not the pieces. Although I don't have to go that way. I could set all 3 piece's center points to the same location, and rotate them, and they would move in unison. But that's 3 times the work.
If it appears otherwise it's an optical illusion, or (more likely) a renderer occlusion, as these were rendered at terribly low resolutions instead of really high ones and shrinking them down before compressing them.
And it's RayDream 5.1. Making the pieces and getting them to align and be the same size and shape was a real trick, seeing as how the poly-drawing tool on it leaves one hell of a lot to desire.
By far and away the best part about the program is the shader. It's VERY powerful and very easy to use... as opposed to something like 3DSMax, which is beyond powerful, but VERY VERY difficult to use.

On Max though, moving the axis is no trouble at all, centering even less (align tool), but like I said, you don't even need to so that if you link them to a dummy object (I don't know if your app supports linking, but logically it should). Then you don't even need keyframes for that, the children can move separately anyway, then when you rotate the parent (which is hidden - or you just apply a 0 specular, 100 transparency material to it and work in wireframe, same diff) they all follow it's axis.
Maybe I'm just picky, I used to rant like a madman on the Raph forums.
Then you right-click to get the context menu for WMP, and reset your file preferences, now, next time you try it should ask you if you want to view it in IE or not. Say no, then it should ask you if you want to open or save. Pick save. Save it somewhere. Watch it.
Assuming you;re on windows, of course.
