Some components get "stuck" When going through the component-by-component install process, a window will pop up for a component and freeze there. It's simply a blank white window with a title like "Freespace 1 training missions" Xing out of it will allow the next window to pop up. Freespace training missions does this, along with awakenings.
After Xing out of the ones that don't work and selecting the files you want, the installer does this

It stays stuck there. I've let it run for an hour and it doesn't move.
If it helps, I'm using Vista. I originally ran the update for an hour or so where it was working fine (except freezing on the Awakenings and FSPort Training missions windows) but had to leave and turn off the computer, and started the installer back up when I came back. I'm going to try deleting everything and starting from scratch to see if that helps.
