I installed OS X Security Update 2012-004, and when my last Folding@home work unit finished, the FAHControl client refused to download a new unit. I've tried deleting the client and reinstalling, but it still won't work. It says: Status: Updating Address: 127.0.0.1 Client: Updating Inactive Occasionally, the screen will change the Status to something else, and my team name will display above a work unit that says "Running" for its status, but then it soon changes back to Updating Inactive and the Identity fields for Name and Team are switched to Anonymous and 0. When a "Running" unit appears, the Project field has some HTML code indicating an Error 500 server error. What did I screw up here?
