Since you're using port 80, do you have skype open and is skype using port 80? If so, to disable:
"Click on the Tools menu and select Options. Click on the Advanced tab, and go to the Connection sub-tab. Uncheck the checkbox for Use port 80 and 443 as an alternative for additional incoming connections option."
Or, you can use a different port, I think fsod might be 8088 by default.
