Unable to open device in Windows

[Crabsoneyes]

I opened up Daemontools, and noticed a new DVD drive had opened in Windows. "Wowee!" I thought.

I then mounted the .iso I wanted to burn (a copy of Cubase), and noticed that the DVD drive had changed icons to a CD-ROM drive. I tried to open it, but I got an error message:

"Windows cannot read the disk. The disk might be corrupted, or it could be using a format that is not compatible with Windows."

Any help?

How did you create the image?
Did you already try another image?
Maybe the image is broken.

I got it from the internet *ahem* , but comments left at the site said it worked ""like a dream" for some people. Is there anything else it could be?
