You can edit the file in a text or hex editor. I've had limited success editing the file with a text editor (notepad may be better than wordpad). A hex editor seems to work better. Still, though, you have to be careful when editing. It's not exactly intuitive. Make a backup copy and play around with it until you figure out exactly what you have to edit. The hostname, computer name, date, time, etc. are near the beginning of the Pro/E file.
