This is user's content issue.

This robot content,

https://www.reallusion.com/ContentStore/ccdproduct.html?contentid=AIC551CIENU000020141024001

causes a crash in iClone when any of the supplied motions are applied to it. It also seems to have a mistake in the AML that comes with it. The right-click Perform is looking on D drive instead of the default content library on C drive.

Steps to reproduce:

Add robot to empty scene.
Apply motion by double-clicking or dragging from Content Manager.

Please see attached GIF.
