Tg Script: Getting Error

Hi MS Users,

I have some problems to run the Tg script by Stephen (Automate calculations for estimating glass transition temperature in polymers). When I try to run the script, I get the following error: "Enumerated properties must be set using string types (InitialVelocities) (function/property "ChangeSettings") at -e line 167."

Could anyone please help with this error.

Thanks in advance.
