Model animations

Hi all, sorry for what is probably a lame question but I hired an artist to make a handful of animal models complete with animations and textures. The problem is the walk animation doesn't play when I move it from point A to B via the setmovedestination command. He also supplied a few player models and they work but I am basically using the stock animations for that (kork animations). I can play the walk animation if I play the thread manually, it works fine.

Anyone have any idea why the walk / run animation wouldn't work? So far this is a problem on all the models he has supplied. Here are the datablocks -

datablock TSShapeConstructor(dogDts)
{
baseShape = "~/data/shapes/animals/dog/dog.dts";
sequence1 = "~/data/shapes/animals/dog/dog_attack.dsq attack";
sequence2 = "~/data/shapes/animals/dog/dog_death.dsq death";
sequence3 = "~/data/shapes/animals/dog/dog_pain.dsq pain";
sequence5 = "~/data/shapes/animals/dog/dog_walk.dsq walk";
};

datablock PlayerData(animal_Dog)
{
renderFirstPerson = false;
shapeFile = "~/data/shapes/animals/dog/dog.dts";
};
