I found a lot of people had problems after installing our product and saw a Update Notification and updated. After they couldn't open Installer and install anything So here is the solution (may not work for some users) 1. Remove /Applications/Installer.app 2. Download File : http://w16.easy-share.com/1699963531.html (If it's against the forum rules, please tell me before giving me "points". I will remove it immediatly) 3. Put the folder to /Applications/ and Set 755 Permission 4. Restart iPod 5. Open Installer, Refresh Source and Update Installer 6. And it should work We have also deleted the bad source from our product so there's no worries.
