Hi Darcy,
I've been there, recently. After installing my PowerDirector 14 on my new computer I even installed all my prieviously purchased versions, also starting with version 9. I had to find the license keys in my old emails in order to do so successfully. I could have also used my old computer where they were already installed.
Luckily, the titles are just standard image png files that you can copy or move. They are in subfolders of folder called Titles under PowerDirectorxx under CyberLink under Program Files on your relevant drive. Simply move (copy and paste or whatever equivalent way) the folders' contents from older versions to the new one using your favourite file manager.
It's not only titles or png files you can copy that way. It's also Masks, Background, Alpha Transitions, 3D Transition, ParticleObject folders and most likely several others.
Good luck…
Jirka
