[HELP] problem running sample

Hi, Run the splitter fine, but when i try to run the sample i get to the "pick your render engine" window, and regardless of which one i pick it does the same...goes fullscreen black, spends a few seconds loading or whatever, then i get this error:

Error #: 6
Function: ResourceManager::add
Description: Resource with the name Ogre/Compositor/BlackAndWhite already exists..


Anyone able to tell me whats wrong? Using ogre SDK should that matter...

You have duplicates in your resource directories.
