"Updating prebinding" is a call to a system tool that, well, updates prebinding. If you forced close, the prebinding likely didn't complete (in some cases, it can take a while - not something we have any control over). If things were "hung", it was likely an I/O error of some sort - perhaps your backup drive locked up, had bus issues, etc?

I'd give it another try with Smart Update and let the prebinding finish...let's see if it gets through after a reboot.
