Hi Mike, The current version of Serv-U is 15.1.7, you can download it from Customer Portal Login | SolarWinds
Whilst I would not recommend using an old version, if you need to get into it, you could try right clicking the tray icon and selecting 'Use System Browser' and make it load up the management console in Chrome for example. However it may stil not fix that,v14 is very old.
Thanks for your response. Using the system tray icon and running it from the web browser worked (well, Chrome did, but IE did not). I am now able to see and edit my users.
Yes, Serv-U File Server 18.104.22.168 is old, but I think this is the latest version I can get. I originally purchased this software when it was available with upgrade protection that never expired. I think Solarwinds took the original software and diverged it into two separate products (Serv-U FTP and Serv-U MFT). This effectively put an end to my rights to upgrade.
Thanks again for your help.
