Hello, good morning. I tried to install an application on my BB Curve 8520, and since then the message APP ERROR 523. I've tried rebooting in Safe Mode, but when I try to backup the device lock, and you can not run the backup. When I turn on the machine the following message Uncaught exception: index 3> = 3
