Actually I was having the same problem...go to Titan's website, they'll explain what's going on.
But when I did move my folders (yay vista) I made sure to put the Titan in first...you see, you might need to reinstall the new Titan, and THEN put in the compatible addons for it next (I suggest re-downloading them, to make sure you are actually getting them to work properly)
Now my Titan works great, even if it's a bit naked from the addons for it that aren't updated yet (hint hint! lol)
