No Icons

For some reason I have no forecast icons when the options under “Skins:Forecast Icons” is set to Classic. When I set it to Bay Area, NY Times or any of the others I have icons. But none with classic. I have the latest (version 5.6) but I have not had these icons for a while now. I tried to uninstall, reinstall but nothing works.

I want my classic icons back! Those are my favorite ones!
