TP5 was working on my machine then I tried to go into the library and it locked up. As long as I launch and enter the library on the standalone its fine . . . as soon as I use the title designer (then access the library) it locks up. So I guess I'm only 50% working.
Titler Pro 5 is working fine on Vegas Pro 14. Please do make sure you hae the newest build installed. If you have any issues, let NewBlue support know. I am working on a new post to add explaining the best way to get everything properly working but will add that as a new post.
