I have just tried it there now and got the slides generated ok (about 33). Is there anything special in the text? For instance, do you have an "&" or any other symbols?
Did you check the auto-animation checkbox.
When i check it, it hangs during slide generation.
When i use all the other options and leave the auto-animation unchecked, It generates successfully.
When i try to add a video clicp to one of the slides, it hangs.
Seems there is a problem with the animation and video (clips).
