the command prompt just shows a load of scrambled chars

If I were a betting man.... you mixed up debug and release libs.

WE HAVE A WINNER!!!!!

@Arcade - it shouldn't overly matter but I've tried either way

@zsbzsb - I suppose its possible, I can take a look

@StormWingDelta - thats all the code there is....if you cant see it, it doesnt exist.

@Arcade - Nope nothing prints to the console, if the picture exists or not it fails, the command prompt just shows a load of scrambled chars before it bombs out...I also agree its likely a runtime error in the C++ redist but I've removed it and reinstalled with no luck, tried official and nightly builds of SFML and I've tried both VS2013CE and VC++2010

The only thing I havent done is try another computer which I'll do in a few minutes

Hi everybody,
This is driving me up the wall, I cannot get this thing to run and I've tried everything, I'm trying to follow the book example from http://www.amazon.com/SFML-Game-Development-Jan-Haller/dp/1849696845 Chapter 1 and I'm getting an error at compile

**EDIT**
If I remove the call to loadFromFile it seems fine, although it does nothing....
**ENDEDIT**

**EDIT**
Oh and I'm using VS2013 community ed, but I've also tried this on VC++E2010 too and I get the same issue
**ENDEDIT**

Error:
