Thanks for the reply Havoc.
Like always, it was a really stupid thing on my part. I grabbed, what I thought, was a back-up disk from my last format. In actuality, it was one from many years ago, so the version of Power Strip I was using was very old and that's why it couldn't detect it. I updated it today and it works now.
Thanks for the info on it being for Europe, didn't know that.
