Thats ok the free version is still a good firewall. At a guess I would say Zone Alarm may be disrupting the connection to the upload space.
When you double click the icon in the taskbar area (bottom right corner of the screen) it usually launches Zone Alarms control panel.
If it's the new version the tab for the logs is the bottom tab on the left of the main screen according to the manual.
If you want to wait till you get home to be stepped through the process then no problem since there is always someone on the forum to help
