Why won't my text field update in the SWF?

Maybe this is an extremely simple question, and I’m just showing myself to be a n00b - but I had to make some kerning changes (space between letters) in one of my dynamic text boxes (it is inside a movie clip on my timeline, so I can animate it - simple animation, alpha change from 0-100, and shrinks from really large to readable).

The problem? When I publish, or even test the movie, the text returns to it’s original setting, rather than the changes I just made.

I’ve cleared out all old SWF files. I’ve cleared and recreated the tweens on the Movie Clip. I’ve done everything I believe I should need to.

So, why won’t the text edit update in the movie?
