Error msg after firewall upgrade

After upgrading the Comodo firewall tonight, I have started getting messages like this one when I click on a URL shortcut. For instance, when I try to open Gmail I see:

Windows cannot find ‘’. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.

BUT the link still opens correctly.

If I close the link location and open it aagain, I get the same garbage msg.

Anyone have any ideas why this is happening and how to fix it?
