,The associated script can not be loaded

Hi I’m new to Unity and I am making simple 2D game for mobile devices. I had 2 previous scripts ControllerScript and Joystick which used to work, but now I get this error and I can’t run the game. I should be able to run the game pretty soon for my demonstration. Can someone help me?

You can reassing this scripts and check if name of class is the same of the file name.
