I'm running the trial version of ESS in may laptop and desktop. I am very much satisfied with ESS' performance as I have tried several security suites. I am considering buying the software but I have one problem, I cannot run the tcalls voip service that used to work before installing ESS. I tried to uninstall ESS from my desktop pc and everything works just fine. The tcalls programs is already in the "allowed" or "trusted sites" but it doesn't work. I tried to swith off the firewall but same story. Can anybody help me please cause I really like this software and my trial version is expiring very soon.
