Just wanted to add that I get the same problem using IE on the server itself, instead of trying to use my workstation. Server is running the default Java version that came with the install.(v7 13 maybe), my workstation is running the most current release of Java 8.60.
Any ideas? Like I said above I can see my content files via the content tab, but when trying to create a new schedule to run and LFD file, no matter how I browse, it see's no content anywhere, not by type, user, name, or otherwise.
