Dev c++ makefile.win error1

[IcantC]

Hi there,
I am trying to compile devcpp project that contains one source file helloworld.cpp

#include <iostream>
using namespace std;

int main ()
{
  cout << "Hello World!";
  system("PAUSE");
  return 0;
}

I get this error: C:\Dev-Cpp\Makefile.win [Build Error] [helloworld.o] Error 1 Compile log is as follows:

Compiler: Default compiler
Building Makefile: "C:\Dev-Cpp\Makefile.win"

g++.exe: helloworld.cpp: No such file or directory

make.exe: *** [helloworld.o] Error 1

Does anyone know what is the problem and how do I fix it?
