My mom has a 2003 iMac and she attempted to update her Real Player and it stopped working. I downloaded the correct version for the OS, followed the instructions carefully, rebooted but the Real Player would not work. We opened the website she uses Real Player for and nothing happened. When the program is double clicked, nothing happens. What could be the reason? Are there filed I haven't deleted? Should I reinstall OSX? It's driving me crazy!!! Thank you!
