You asked specifically about the incomplete folder. Items in red in other folders/windows can mean other things. In your Library window the other folders that have items in red means they aren't being shared (other people can't downld them - usually a refresh will fix that.) Or of course when you 1st start LW all your shared files start off red b/c LW hasn't yet accounted for them all ... but they eventually turn black.

In your search results, any item in red will mean it's behind a firewall. The older versions of LW would have had only a small chance of successfully downlding from those sources. But the newer versions of LW are much easier to downld from firewalled sources. Not to say you might not come across some difficulties. I've successfully downlded from many a firewalled source.
