Moved portal to root, fck browse buttons broken

I moved my dnn portal from a subdirectory to the root. Now when I use the fckeditor and I try to insert an image or anything else that requires me to browse, I get an server configuration error telling me that the code subdirectory '/Providers/App_Code/HTML/' does not exist. The path it really needs to find is '/App_Code/HTML'. What is broken and how do I fix it?
