I download games off a site Mor@#$ in a ISO file "grand theft auto San Andreas" and a couple other games. When I open it with ISO buster I get the message "no file systems and or files found" Or if I open with DVD Dycrypter I get "Invalid or Unsupported Image File Format" Am I doing something wrong or are these files no good to start with? Thank you for any help for this "newb"
