I have 184.108.40.2060 running on one PC and 220.127.116.111 running on another. Everything is fine with the 18.104.22.1681 version - I just did a manual update and received definitions version 789. However, my 22.214.171.1240 version is NOT getting definition updates - it gives me a Network Connection Failed error every time I try, yet it can open my browser to say that my program is up to date. (I realize that the definition updates and program updates are separate things.) I turned off my firewall and AV and still get the same error. I uninstalled 126.96.36.1990 and reinstalled it and still get the same error (tried it both with FW/AV on and off). Any one else having this problem?
