TLB not opening on startup

I posted a message on this a few months back when this was happening to a friend of mine and what you told me to do to fix it worked on my friends but now its happening to me. The things you suggested being looking for 3 keys in the registry and deleting them isnt working for me cause those keys arent in my registry so I am ata a loss. Whats weird is I have 3 TLB bars the standard quicklaunch and 2nd bar that open on the taskbar and a 3rd bar that opens at the top of the screen. Well the one at the top of the screen opens every reboot but the two on the taskbar refuse to reopen on a reboot I have to manually opn those dunno what happened but any help would be greatly appreciated.
