A person asked—if I take the free download in its slightly scruffy state…

…will I be able to download the improved free file on Closed Circle when it opens?

Absolutely. A free file is a free file. As far as I can figure, the software is going to let you download that as often as you like. Experiment away and get used to the pc/Mac reader-software, conversion software, loading it on your reader, etc. Eventually you can just toss that one and get the cleaned up version from Closed Circle itself.
