I get the following error dialog box after running Tiny Umbrella: "Something is wrong: You don't have admin priviliges or you have something running on Port 80 or your host files are not modifiable. Please check Anti-Virus software or shutdown Skype/teamviewer/etc as these apps block access to Port 80" I have no anti-virus software (using Mac with Snow Leopard) and I don't have Skype installed? And I'm logged in as admin. Any suggestions? I'm trying to use Tiny Umbrella.
