8703e JVM 523 error

I downloaded a Metallica wallpaper from Crackberry to my Blackberry 8703e. I had set all the icons on the homescreen to hidden. When I tried to show all,it gave me JVM error 523 Reset
I made a backup a few months ago, hopefully that is good enough.
This is my workphone and now I cant access the application that I need to. Hoping to avoid getting in trouble over this.

**Update**
I restored to my last backup. Everything seems fine so far. I would recommend,as I will do in the future, that before any changes to the blackberry a backup be made.
Unfourtunately, my last backup was May and I just lost phone numbers and emails and memos and who knows what else that I wanted.
