That is really annoying, but I was just guessing. We need more information. First of all, what "text effect" did you use? PowerDirector does not know "text effects". If I go to the "effects room(F4)", there is no text effect. So I guessed that you used the "title room (F7)". But I have far over 100 texts. Which one?
Or do you have a title and try to use an effect on that?
What was the steps that you did? And did not work? Maybe a sreenshot of your timeline would help.
If the error is not obvious, we need information to readjust that error to help you.
