This means you don't have JavaFX. If you are running Java 11, you need to download JavaFX separately from https://gluonhq.com/products/javafx/ (path configuration instructions are here). You should then be able to run it with:To avoid this mess just install Oracle Java 10, but I believe that has been discontinued.Code:java --module-path $PATH_TO_FX --add-modules=javafx.controls JNoexsClient.jar
Goodness gracious, I just did a full reinstall and was planning on doing this, when I literally just remembered I probably had JRE 10 still in my downloads folder. And it's there.
Thanks for the help though. Might just throw it on filehippo or sourceforge for others.
