Error reading audio files - Running the release .app file


I’m creating a project that uses ofxPDSP for some generative music. I have from drum samples to load in which are saved in my data directory. When I run the program from XCode, they load up just fine, but when I try run the Release .app that is created in the bin folder, the samples won’t open. Do I have to save them in a different place, or change how I’m referring to the directory?
