		The Hardware Simulator won't load the mux chip I made. I independently checked the Or, Xor, Not, and And functions and they work but the chip wont load. I had this issue before and I deleted and redownloaded the who set of projects twice which fixed it but it keeps happening and I don't know why. I am following the order of the components in the book and only using those components. My Mux.hdl file is below.
  // This file is part of www.nand2tetris.org
 // and the book "The Elements of Computing Systems"
 // by Nisan and Schocken, MIT Press.
 // File name: projects/01/Mux.hdl
  /** 
  * Multiplexor:
  * out = a if sel == 0
  *       b otherwise
  */
  CHIP Mux {
     IN a, b, sel;
     OUT out;
      PARTS:
     // Put your code here:
     Not(in=sel,out=sel1);
     And(a=sel1,b=a,out=o1);
     And(a=sel,b=b,out=o2);
     Xor(a=o1,b=02,out=out);
 }
