Dan, what build did you previously have installed? What build do you have installed now? What video card/video driver version are you using? If you start a help ticket at newblue.com with the answers to those questions, we'll definitely try to help you.
I had the same problem when I first installed 120718 over the previous version. I then first uninstalled the existing NBTP, rebooted, and then installed the new version. I have been running the system for the last couple of days with no crashes that were related to title program. Just a thought.
Yes, it certainly never hurts to uninstall the old version before installing the new version. It also never hurts to reboot before uninstalling/reinstalling because, sometimes, Vegas doesn't quit running when you exit it.
