I'm not sure what 'relative path' and 'full path' mean;
Full path would be somethign like c:\games\bob\cool\image.png
Relative path would be something like cool\image.png or ..\cool\image.png
So one question is in your code where you are loading resources which method are you using?
I'm assuming relative path so you need to make sure your .exe is in the right place to "find" the resources by following the "path" laid out in the code.
