Hello! I am working on a project for a competition, and I'm trying to export the game I've created to a .jar file, to not have to have Greenfoot installed when I present it. I fully coded the project in Greenfoot 3.8.2, and then uninstalled it and installed Greenfoot 3.8.1 so that I can export it as a .jar. No matter what I do, the .jar file will not launch. I've uninstalled and reinstalled Java, I've used jarfix.exe, but it doesn't work. I can double-click the program as much as I want, it is useless. Even unzipped the .jar file to see if it works in Greenfoot, and it does. This is the download link to the .jar: Download of the Jar Any help would be greatly appreciated!

Hello, my Solitaire scenario (https://www.greenfoot.org/scenarios/33256) that I published recently does not work properly on browser but works perfectly fine on Greenfoot app as I tested by downloading it on another computer and my own computer as well and I also tried using other browsers. From what I see so far everything breaks after you press play on the main menu on the browser. I made this scenario long ago so I don't remember much currently try to fix it but any help will be greatly appreciated.
