BB Messenger not installing/working!!!
 

I have the Curve 8330. I recently upgraded to the 4.5.0. When I did that it knocked my BBM crazy! I have the icon but when I click on it, nothing happens. When I go to applications, it's not there, and when I go to app world to download it again, it gets to 3369 (not exact) out of 3369 then my phone shuts down. And again I am back at having the icon, not working, not in applications. I have gone to App World and into my apps but you guessed it...not there!

What else can I do to get my BBM back on my phone? :?
