If you have already installed the BlackBerry CD on to your computer desktop, go into that and then click on the applications button, there you can delete the affected app and your phone should return back to normal when finished. You may have to download BB App Store back onto your phone after you have done this. Hope this helps you.

I am getting this error aswell, the phone would load and load continuesly and i would pull the battery and insert it again, after the reboot load bar has finished loading i would get the app error 523 instantly, i have used the device manager to remove programs but im unsure how to decide which application should be removed, should i remove the application i last installed or updated or the application that was last used or in use when i had to reboot the phone
