Script to Provision SharePoint MySites Prior to User Login

Hi,

I have tried to use a couple of the different scripts I have found on the web to automatically find all the user profiles that have been synchronized from AD and provision the My Sites prior to the usre logging in.  However, I keep getting the same error when trying to run any of them.  This is on Windows Server 2013 with SharePoint 2013 Enterprise.  My Site Host is setup and if a user manually goes to start their My Site it will provision for them.  The user I am running poershell as does have full control of the User Profile Application Service.  Code is attached and here is my error.  Any advice?

Add-PSSnapin "Microsoft.SharePoint.PowerShell"
