I am sorry to hear about the circumstances and hope that at least my answer is helpful: There are two ways that I see likely to be successful: 1. Download an old version of Greenfoot (the version with which the scenarios had been created 10 years ago) and run the scenario in this old version. or 2. Adjusting the scenarios to the current version. Details: 1) === Download old version === If you click on the "Download" button above, you get to the Download section. There, on the bottom, there are links to the "version history" and "old versions of Greenfoot". "version history" will help you determine which version you used 10 years ago (e.g. it says "Greenfoot 2.1.1 (8. September 2011)") Then you can download that version at "old versions of Greenfoot" and run the scenarios in it. 2) == Adjusting the scenarios == For this, the question is what the differences are. So, what are the error messages that the scenarios give when trying to compile or run? In best case, it is probably just that the old scenarios used "java.awt.Font", but now "greenfoot.Font" has to be used. (see "conversion guide" link at version 3.1.0 of the version history) In any case, I think here are some people that can help you when they see the actual error messages (or description of what exactly goes wrong when trying to access the scenarios). Live long and prosper, Spock47
