My iTunes will not open on my Macbook. I have tried deleting it, downloading it everything to get it to work but when i try to open it a message comes up. "The iTunes Application could not be opened. An unknown error has occurred. (13010).
Try removing the Genius database. In the "Finder" go to the /username/Music/iTunes/ folder and delete the "iTunes Library Genius.itdb" file. This may allow the program to launch again. This file will be recreated upon first use of the "Genius" feature.
