Unfortunately, it appears the links no longer work? At least the dropbox link for "KindleComicConverter_win-amd64_2.5.zip" doesn't. :\ Was looking forward to using this, as I just received a Kindle Paperwhite. Look forward to hearing from anyone with new working links!
Btw, I did do a quick google to see if there were alternative links to no avail. Still linked to the dropbox, and it's 404'd.
