Any pointers for this:

Cannot convert argument "pszProfilePath", with value: "System.Management.Automation.PSReference1[System.Text.StringBuilder]", for "CreateProfile" to type "System.Text.StringBuilder": "Cannot convert the "System.Management.Automation.PSReference1[System.Text.StringBuilder]" value of type "System.Management.Automation.PSReference`1[[System.Text.StringBuilder, mscorlib, Version=4.0.0.0,

Need to remove the [ref] on $pszProfilePath on line 14

Removed the ref.. now the darn thing blows up Shell..... HMM
