Hey, 
Related to my last post, requesting and update to the Omnivese_Audio2Face Plugin, I'd like to suggest, that at some point, we update the plugin to catch exceptions for the index out of range error and post to the user a hint about possible causes in case it is a "user error" when generating/exporting the blendshape animation from the Audio2Face application.
If it is not the plugin that is in error, it would be helpful to know what to do in the A2F application to prevent the error.

Just thinking,  perhaps it's a good idea :)
