OK, go ahead and post the complete log rather than an excerpt and we’ll see what it says. The error you posted is weird because it seems to think that mainBundle is the folder above the sample app (../OpenEarsSampleApp.app) and I doubt it should be referencing that path using OpenEarsSampleApp as its reference point at all, let alone a directory that is outside of the sandbox. Have you made any changes to any part of the code relating to that path?
