Here is the full log file: This looks exactly like the issues we've seen with broken antivirus or personal firewall software. Make sure you don't have any such installed (actualy installed, not just enabled), and if you do try to uninstall them. If you don't, but had before, check for any remaining pieces. There should be posts in the archives with details about it. Again, note that just disabling things usually isn't enough, you need to actually uninstall. //Magnus
