Ok, so probably need to try installing the new animations directly into your game.
Download them here:

You need to download them to your data\ballparks\models\misc\player folder, restart the game, and hopefully that should fix things.
The next patch will also add a few more checks so that the game at least won't crash when you're missing them.
Thanks to Matt for the above btw, I'm just more or less copy/pasting from one of his posts
