Well, look at everyplace where you have the signal zerox.

   //// Mux16(a=x, b[0..15]=false, sel=zx, out=zerox);
        Not16(in=zerox, out=notx);
        Mux16(a=zerox, b=notx, sel=nx, out=presetx);

The first is commented out, so it doesn't apply.

The other two are inputs to various parts.

So there is no output of any part that is establishing the logic level on that signal, hence the error message.
