I’m a little concerned about the crash with Titler Pro 4. I had the same problem with both SVP13 and Hitfilm Pro 4. Turned out the order of installation was important for Vegas: remove TP4, install Vegas 13, then TP4. I also had to make all old versions/folders of Titler (Titler EX, etc) were off my disk and out of the VST plugins folder. Maybe this will work for you?
