VS11BETA
I do not know much about VS configuration

[Torin]

Make sure you're using the console subsystem. Go to the project configuration window, and into the Linker section (I don't know the exact names for the latest VS), and select /SUBSYSTEM:CONSOLE in the Subsystem bit (again, I'm not sure what this will be called).

By default, it's probably expecting you to use WinMain.

(The entry point of a program is the 'main' function basically)

that was it, fixed
