Happening also now to me.
Avid MC 6.5 and OS 10.7 on a MacPro.
I just get an error message “AvidTitleTool cannot be opened because of a problem.” Neither Marquee nor the title tool will open.
Did you ever find a solution to this?
I already tried a new project and a new user profile, but neither worked.
Thanks so anyone who can help me with this !!!
