Hello all, I am new to ArcGIS Server 10.1 and the ArcGIS Viewer for Flex. I have come across an issue that I cannot seem to resolve. When I try to access the ArcGIS Viewer for Flex application builder, I keep getting the error "Please Check Your Base Folder URL". This URL was working fine previously and allowed me to access the application builder, but all of a sudden stopped working. Is this perhaps an issue with the server itself?
