I am trying to download some audio from my Olympus DM-20 voice recorder, which I have not used since I installed Mountain Lion. During the installation, I run into a "Setup.app" which apparently can't be opened "because it is from an unidentified developer." When I open the setup.app, I notice that the date on it is 2009. Could this be the problem?
