I got it working by disabling my newly installed Skype. I dunno what ports Skype uses, but as soon as I disabled it, my UniformServer worked again. YMMV
Ditto for me. FWIW, I have been running Uniform Server for the last 3 years and am delighted with it (THANKS!). The new security patch might have disabled something???? I have d/l'ed the latest versiona nd it fails without any error messages, even when ececuted from a command line. Thoughts? David
