No, looks like the reply is still stuck in the outbox for some reason, and refuses to send.
tk2dStaticSpriteBatcherEditor.cs, line 20, change it to:
allTransforms = (from t in allTransforms orderby Camera.main.WorldToScreenPoint((t.renderer != null) ? t.renderer.bounds.center : t.position).z descending select t).ToArray();
This will sort the sprites to the main camera in your scene.
