In my case since build 798 autoupdate of rf2 does not working. update and verify buttons are death, the black window is empty. The game is installed on main disc, my os is win 7, cpu i5 2500k, gpu gtx 760, 8Gb ram.. When I start manually SyncManager, gives me information "Sync did not complete. Source directory, core directory or data directory may not exist" Game works perfectly... only this problem.
