I just had the same issue with my copy of PP CS6. Fortunately I had already completed the project and had to correct 2 typos, but I kept getting the same error message and it kept crashing. I finally managed to make the corrections despite the titler issue. I was still having issues with any new projects I created and trying to use the title tool, so I ended up uninstalling/re-installing PP and now everything works fine…except that old project! Thankfully new projects are ok, just that one problem child. I don’t know.
I did update some drivers a few weeks before the issue started, but nothing to do with any of my Adobe stuff. Also, I’m working on a HP ZBook 17, I7-4700 2.40GHz, 16GB, Windows 7 Pro and plenty of HDD space.
