ControlP5 isn't a core library (shipped with Processing itself), so I move the topic.
Note that you show pure textual information, so copy & paste of this text can be faster and easier to examine (and works with search too!) than showing a big image hard to read (I change my colors in the PDE because I have trouble to read dark red on black background).
Perhaps you use a version of CP5 that isn't updated for the version of Processing you use.
