Your firewall software is probably blocking Camfrog from accessing the Internet. Go to add/remove programs and uninstall Camfrog. Now go to your firewall software and remove Camfrog from the allowed applications list. Reinstall Camfrog and when your firewall asks you if it may access the Internet press "Yes". Unfortunately some firewall software does not work correctly so when you upgrade to a new version of Camfrog from 3.0 to 3.X the firewall software doesn't realize this is the same program, so you must delete it and re-add it to the list. If you still cannot logon to Camfrog and you have no firewall software installed then there is probably a temporary network problem with your service provider, or a temporary problem with our server.
