Upgraded from ZA ES to 11.0.768.000. This caused Anonymizer Universal 1.3.1 to start failing connection attempts with Error Code: 651 complaining that the "modem or other device returned an error". FWIW, my connection is through a FIos ONT not a "modem". I made sure the permissions were correct and that the IP addresses of the ports were okay, but that was as far as I could see to go. I ended up "rolling back" by de-installing 11.0.768.000 and re-installing AU 1.3.1 now works again. Any ideas why (or what setting(s)) I should look at to get 11.0.768.000 to share the sandbox with Anonymizer?
