Answer 1

An Error occured at your Authentification process (line of $objAcc =), maybe wrong password or username.
Maybe if an error occures, the .Get Function of the WMI Service don't returns an object.
Check for Errors like this
if(#error <> 0) Then
; ERROR HANDLER
EndIf
And check if the account informations are correct.
