If it just downloaded and nothing else then you probably dont have a manager installed for it to use, if you do its setup wrong.
For anyone else, you can read the scipts code once you follow the installtion, this is fearmongering at best due to not setting up correctly.
I clicked on the download and nothing happened except it acknowledging I downloaded it. I don't want this to potentially infect my browser or steal my passwords, so I'm about to complete a fresh install of my browser just to be safe.
