I also get that error. in addition non of the animations or gallery load. I hear the sounds but only a tiny box appears when the animation should be.

This error message happens when you press "Load Game". Pressing "Ignore" still lets you continue and play, so not a big deal. Still wanted to point it out so you know about it.
