This isn't a thread about Jnes actually. Secondly since you are posting anonymously your email address was temporarily caught by the spam filter, it tells you this after you submit a post, be patient.
Lastly insulting my fixes won't solve your issue, nor does it encourage anyone to help you. There is no technical support for free software, you have to do some of the initial troubleshooting.
Jnes is not distributed on a DVD, there may be something that prevents it from saving to disk properly, the Settings page in Jnes tells you where this it is trying to save, make sure that directory is writable, and you are using the latest version.
