Hi Dreemr, welcome to NST.
Did you follow the
instructions on downloading torrents ?
Was the download a single .ISO file ?
If not, check that your folder options are set
thus so you can see the file properly, and
don't process the file in any way. If you're seeing it as a compressed file and unpacking it, you probably have ISO associated with winRAR or somesuch app.
The downloaded file
is an ISO and must be burned entire and untouched.
