Hi,

just replace

Model -> "UnitarySM",GenericModel->"UnitaryLorentz"

in diagsMuonDecayTree = ...

with

Model -> {SM, UnitarySM},GenericModel->{Lorentz, UnitaryLorentz}

I'm not very eager to fix that old example, since for the upcoming
version of FeynCalc most of the examples have already been reworked and
renamed in a proper way:

https://github.com/FeynCalc/feyncalc/tree/master/FeynCalc/Examples

Cheers,
Vladyslav
