Hi Ray!
I am not an expert (just a copywriting student) but I think you've got a wonderful start!
Personally, I think this should be your main headline (instead of having it further down the page), if you are targeting folks like me who plan to publish their own informational products:
At Last! Introducing the File Secure Pro™-A file security system that is 99.99% effective against illegal theft of your PDF documents and Ebooks …
Just curious... why did you put the bulleted facts in quotes? You're not actually quoting anyone, right? (I know quotes are used to make headlines more attention-grabbing, but I don't think it works the same in this case.)
You say something about not charging a flat monthly fee like others, but then you mention $17... being billed every 30 days... that's confusing to me (yes, I are a blonde

) and sounds contradictory.
Your sales letter has a few errors here and there, but it's obviously still a draft and I'm sure you'll catch them when it's carefully proofed.
Overall, I think it's very compelling copy and you've done a great job! I hope you get some additional comments from the "experts" in this Forum, as well.
