Good to go, i used WinZip like you said. Cheers
@Guidostrunk I had the same problem. What you need is to unzip the file. You can get a free (well, evaluation period) copy of WinZip here. If you're on a Mac, the software is Stuffit. Once you've done that, it goes like a dream.
And now I'm a believer. The sound is amazing.
