BB Curve :: No Icons On Main Screen Of My 8320

I think I accidentially deleted something & then suddenly all of my Icons on the main screen dissappeared. And all I get is a blank yellow circle that I can move across the bottom of the Screen. Also after the accidential deletion, I intermittently got "Error 523" with "Reboot" or something like that. On the secondary screen where it would normally display all Icons, I only get a blank screen (just showing my background) with no icons. It does however show stuff like the battery symbol, notifications, wifi symbol, etc.

I reinstalled the most recent firmware that I could reinstall.It restored the Icons on the secondary screen but none on the first screen and still only get a blank yellow circle that I can move back and forth across the screen. & I also lost the ability to "move" Icons. Even tried "Alt+BB button" & not able to move Icons,I took out the battery, Sim card & memory card & then reinserted them. Still no Icons on the first screen & on the second screen where all the Icons would show is now blank again.Anyone know how I can restore the Icons to the first Screen? How I can get the move function back & get all my Icons to not dissappear off the second screen?
