Newblue VideoFX for Sony Vegas MSPPS is installing two software files which (can be seen in the uninstall folder) causes the program to Crash. It also happens in Vegas Pro 11
If you have Vegas Pro 11, you should be using Titler Pro 1 instead of the MSPPS package. Do you have Titler Pro 1 installed? You can't have both Titler Pro 1 and the MSPPS package with TitlerEx both installed.
