So the problem now is clearly that you are missing the .MGU files for some reason.

1. Please download this updated patch and see if it fixes that.

2. When you run the patch, make sure that you are selecting the correct Drums folder location. It needs to be the location that you took a screenshot of in your last post. I'm not sure if you are using a custom location for Drums.

Please report back and let us know.
