I just experienced the same issue after opening a project that I created years ago. Same problem with the titler:
CS6 Titler is corrupted: /src/VideoFrameFactory.cpp-78CS6 Titler is corrupted: /src/VideoFrameFactory.cpp-78
The titler worked fine in newly created projects, just not in that old one.
Then I did some experimenting – copying all project items into the clipboard, and pasting them into a new projects – titler working.
Then I stripped the project down to one title and did a node by node comparison of the written .prproj files (since they are simple XML). And after some replacing I found that the issue was caused by the <WorkspaceDefinition>. When I copied that from the “newly” created project to the defective one (replacing it there) that project also worked.
I suppose that it must have been saved, when I had a different monitor configuration – and the titler has problems with it and needs a fresh one to work again.
So in the end I found this simple repair:
-Open your broken project
-Open the menu Windows / Work Area
-Click Reset current work workspace..
-Save your project
-The titler schould work again
CS6 is a bit old nowadays, so it’s doubtful, that this solution will benefit many people. But some times it is necessary to open an old project (like in my case). And I thought it’s good to know, what to do then.
