Unknown Application Icon for Favicons showed up

The other day my favicons for my favorites turned into the unknown application icon. You know the one. The one that looks like a white sheet of paper with Window in that and 6 tiny icons in that window.

The icon that does not know the application that created the file. I don't know why my favicons did this. I still have some folders that I created there and in those folders that same icon is in these created folders.

So there not even an Internet Explorer E, they're all the same unknown application icon.

So I have tried to resave the favicon or website favorite but they still show up the same unknown application icon. Let's call it a UAI.

So what's up with that?

O BTW, I went two TweakUI( I am using Windows XP) and hit Repair Icons. I was in Windows Explorer looking at my Favorites and the icons went back to the normal favicon but only for one second and then went back to the UAI icon again. About 6 icons out of 30 turned into the Internet Explorer E though and stayed.

I have deleted and tried to save a favorite and they are still the UAI.
