Silgrad Tower from the Ashes

Hi, recently I downloaded a large file and it's compressed into an "nrg"-- I've never seen or even heard of this type of file before. Does anyone know what program is needed to open it?

Daemon Tools can mount them.. or Alcohol 120%.. Or use Nero to burn them to a CD.. A .nrg file is a Nero CD image file.

Thanks Krisi, its working now.
