My laptop has completely crashed - cant access anything! I have all my data files backed up on an external drive so I can find my .NOD files . However how can I re-install NOF 15 on my spare laptop? I bought NOF years ago and have upgraded through the various versions to the latest version 15 but don't have any of these installation files! How can I re-install NOF 15 entering my license key so that I can use it again? I don't want to have to pay c £100 for a new version when I have effectively paid hundreds of pounds over the years through various upgrades!
