Did you download it from the thread? U need to download it via local and not use the SDN version. As it needs to be updated. I have checked several times with 2 different VM's and it is cursing then alching and repeating perfectly fine
NOTE: I think if you have the local script and SDN script with same name, it might clash. You may need to remove the script from the SDN in order to get the local one to work.
