Warner,
Re-read Kyle's points.
Your words just didn't flow well, so I would swear you either couldn't write or had a bad case of block when you did this. Word flow is just as important as all the other page elements...especially with this product.
I would also work more on one of two things (or maybe both). I'm talking about the way you describe the writer's block condition...or possibly the way you describe the cure. I think either one could work. But it's not enough to say "I had it, and now I don't."
I think the use of metaphors could really help this copy. For example, get into how nice it was to be able to write again--
"It felt like I was flying...the words were coming out so beautifully, they were flowing as if I was pouring water from a fountain"
Something like that.
On the other extreme, you could dive more into the problems of writers block, and how much of a pain it is. Maybe mention deadlines, nagging editors, nagging clients, nagging doubts in your mind. You can find a good example of this here:
Eric Engel - Who is this guy? » Blog Archive » Writer’s Block…a sad story
But then, I don't think this is the best route...as writers already know how much of a pain it is. They would want to hear more about solutions.
