Win7 x64 Admin
No virus checkers or firewalls active.
If I select files from a group and "Save Files to Custom List", whether an existing list or a new list, none of the files show in that list.
Filters on or off, show all posts or only display age, show filenames and hide old toggle..... Nothing make the files visible.
If I select the same files in the group and "Create NZB from Posts" and then load that NZB I can save the files from the NZB to my custom list and all is well.
I have uninstalled Newsbin, deleted the remaining data folder, deleted all entries from the registry, rebooted and did a clean install adding all my severs,groups,filters etc manually and get the same result.
There is nothing special about my computer, I run a lean system with only Firefox, Excel,Word and Newsbin. No games or background crap. All drives are fixed and I run as admin so permissions have never been an issue.
In over nine years of use I have never had a problem, until now.

Cheers.
