Debugging information cannot be found or does not match

I wanted to try learnign some C++ with Visual C++ Express but when i try to build even the simplest program:

#include <iostream>
using namespace std;

int main()
{
   cout << "Hello world!\n";

   return 0;
}

I get the error below:
Debugging information for "project.exe" cannot be found or does not match. Binary was not built with debug information.

To enable debugging:

1) Goto Project->HelloWorld Properties
2) On the left expand "Configuration Properties"
3) Expand "C/C++"
4) On the left, Select "General"
5) On the right, change "Debug Information Format" to "Program Database For Edit And Continue (/ZI)"
5) On the left, Select "Optimization"
6) On the right, change "Optimization" to "Disabled (/Od)"
7) On the left, expand "Linker"
8) On the left, select "Debugging"
9) On the right, change "Generate Debug Info" to "Yes"
10) Click ok
11) Set your breakpoints
12) Rebuild your application

Also when running your application use Ctrl+F5 to build and run it, this keeps the console window open long enough for you to see your output.
