I started testing the free product today, it is excellent. I am having a bit of trouble with the published version of my text being offset to the right, about 190 pixels across a 720 pixel (x) stage. I have CS5, usinging dynamic text, and have embedded the font.

Take a look at the FAQ section and you will find the answer there:
"Q: The Target textfield's position changes while the animation is playing.
A: This malfunction appears when the target texfield is initially created as a Static textfield then converted to dynamic textfield . To ovoid this problem, the textfield needs to be set as a dynamic textfield before creating it on the stage."
