VideoStudio :: Adding Title To A Clip?

I am using VS Pro X4 for quite some time. All of a sudden today, I was not able to "add a title" to a clip. It was working fine yesterday. Whenever I clicked "T" for "add a title to a clip", it switches from "Clip" to "Project" and although the "Double click here to add a title" was shown obviously nothing happened because it was in "Project" view.

After Brian told me that it always go from Clip to Project when clicking "T" or double clicking the Title track, that seems to be normal.. After using VS since VS 9, I have not noticed that before (if something works one usually does not notice anything...).

After re-installing VS Pro X4, per instructions in corel.force.com "How to remove X4 manually", and reinstall it, I am still not able to add text to the clip. Clicking "T" or double clicking the Title track still gave me the "Double click here to add title " notice in the preview window, but nothing happened upon double clicking the Preview window.

Out of curiosity I also ran VS X2 ,that is also in my computer, and with X2 the same problem exists --> no text can be added to a clip.

Back to VS Pro X4, however, I am able to drag a VS pre-set Title clip (Lorem Ipsum) to the Title track and then modify the text. So, if I could not get the problem solved of adding text directly to a clip, I have to add text the long way through the preset Lorem Ipsum clips.
