Hallo to all, I purchased ESS 3.0, installed it and it was working great. ESS updated without problems. But now after reboot my pc can not get an IP from router. After installation ESS detected my network correct and added it into the trusted zone. e.g. 192.168.178.0, 255.255.255.0. When I click on the icon of the network card I get information that no tcp ip driver is installed. But there is an additional driver of ESS on the network card. The network card icon shows that I have connection to a 100 MBit network. So it is not a problem with my connection. I tried setting an fix IP to network card but same result. No IP from router. After uninstalling ESS again I can go to internet without problems. On my pc I am using Windows XP SP2. No other antivirus or firewall is installed. Has anyone an idea what's the problem ? Thx for an answer.
