Issue with the capacitive sensing project in processing and serial monitor

Hi, I have an arduino Uno, and I am currently working on a science fair project related to the capacitive tracking project here. My science fair project is due in 3 days(don't judge me!) because i had ordered parts for another project and they are to be shipping from china in like a month, so I am working on this for my project. I built the whole thing, and then I ran the arduino and processing sketches and nothing worked. I know that the serial monitor is at 112500 bauds and the serial monitor prints just one 0. the processing sketch causes an error and the exported .exe file is just a grey window. The error is

please help i need this by march 24th

Are you expecting the Arduino to talk to the Serial Monitor application or to the Processing application. Both is the wrong answer. So is yes.
