http://localhost is fine. http://localhost:7030, as called by Network Probe 'Start client' takes me to the login page but as soon as I log in, I get nothing but a completely blank page in Firefox, and 'Internet Explorer cannot display the webpage' in IE8.
I am having the same problem. i tried loading network probe as administrator and still did not work ( Internet Explorer cannot display the webpage). System Win 7 64 bit, running latest JRE (32&64), loaded with signed drivers disabled (which btw is a pain too, not to mention not secure). Popups are allowed... what else is there to try?
