installer.app broke :( howto reinstall?

[prophet]

I updated the installer app a few days ago and when I try to launch it now it shows a white screen for a sec and disappears... anyone know how I can Fix this or reinstall the installer.app?

I wanna know this too, my installer closes right after it opens. I'm using 1.1.2 unlocked using AnySIM.

I downloaded the new AppTapp and took the Installer.app from the package content and put it in the Apps folder and tries to launch it.. It disappears sometimes..
