Need help with using SpriteManager2's animation

Hello all,
I'm using SpriteManager2 1.7 on Unity iPhone Advanced 1.7
My question is, can I play a sprite animation when using a Sprite is under a Managed state?

I tried:

Code (csharp):

1. sprite = gameObject.GetComponent(typeof(Sprite)) as Sprite;
2. spriteManager.AddSprite(sprite);    // spriteManager points to the SpriteManager within the scene
3. sprite.Managed(true);
4. sprite.PlayAnim(0);
5.  

PlayAnim seems to be working on a Batched state (when managed=false)
but couldn't make it on a Managed state.

Any pointers?
