How to fix faceplus MoreBlendshapeMeshes error in unity3d v4.6.1

I've been trying to make some facial animation with Mixamo faceplus v1.1.0.4 using this toturial (https://www.youtube.com/watch?v=JtcVl218CBE), but every time i start calibrating my character this error shows up:

ArgumentOutOfRangeException: Argument is out of range. Parameter name: index System.Collections.Generic.List`1[System.String].get_Item (Int32 index) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System.Collections.Generic/List.cs:633) FacePlusExtras_MoreBlendshapeMeshes.FindCommonPrefix (System.Collections.Generic.List`1 stringList) (at Assets/Mixamo Face Plus/FacePlusExtras_MoreBlendshapeMeshes.cs:25) FacePlusExtras_MoreBlendshapeMeshes.Start () (at Assets/Mixamo Face Plus/FacePlusExtras_MoreBlendshapeMeshes.cs:51)
