I purchased the LEGO Mindstorms NXT Green City Challenge Pack on LEGO many years ago. Now, I wanted to use back this challenge pack, but I found that I've lost the CD Rom and the class that I am using this for is going to start in no time. How could I get a replacement copy of the CDROM only?

If you are missing a component of a set supplied by LEGO Education, you have the following options:

  1. Contact LEGO Education support (different support line than the regular LEGO service support line) at https://education.lego.com/en-us/support. Their US telephone number is 800-362-4308. Plead your case there - they might have a digital copy or remnant copies on hand. You would likely need to provide details to make sure you have bought the original package (e.g. your NXT license number).
  2. Look on second-hand marketplaces such as BrickLink, BrickOwl or EBay to see if someone is selling the CDROM. I have looked for you and can only find 1 complete Green Challenge kit at the moment of writing this answer, so this route is not feasible.
  3. Asking for someone to make a copy of a copyrighted work is (at least in most countries) illegal, even if you once purchased the original.
