This again seems to be an issue with an image somewhere along the line, there's 3 things I'd suggest: - Make sure you're using the latest version of Greenfoot, errors like this suggest you're probably not and upgrading often solves issues that've been fixed. - Make sure all your images are referenced in the correct case, eg. if you type "pic.png" in your source code and the image is called "pic.PNG", this can cause problems like the above. - Make sure all your images are inside an "images" folder in the project directory, this sometimes helps.
