After adding a second Usenet server my Newsbin Pro UI would no longer update and the program itself seemed unstable.
I decided to re-install Newsbin Pro 6.42 to see if that would fix things. I got an "Internet connectivity is required for this installer to download the latest program executables." error message. I have full internet access, however the newsbin.com website appears to be offline. I can only assume that the website being down has affected my ability to re-install it.
