Hit shadowman1.rar to unzip the image file.
You can use WinRar or
7Zip to do this.
Use a new folder to store all the files that are in the archive.
You don't have to 'create' an image file, the CD image is in the archive.
The post in the ISO cellar says it's a Clone CD image, so you'll get several files.
One of them should be a *.CUE file.
Use "Write image file to disk" option in ImgBurn.
Point ImgBurn to the CUE file to burn the CD.
[Edit]
Now that I think about it, before you try to burn the CD maybe post what files you have.
Sometimes the providers use an extra compressor.
Can be ECM or such ..... then you need to do an extra manip before you can use the image.
