    Are you using an IDE or how are you trying to start the client?

    Build as what? A jar file? Or just when you start the client via debug?

    Even though you Jar the client yourself. Can you run that Jar or does it not open either?
    I forgot what it is exactly but I think compile path needs to be changed.
