When updating to the newest version 1.1.42, it seems there is a problem.When clicking the bittorrent sync icon I get this message: It seems like BitTorrent Sync is allready running, but not responding. Please close all BitTorrent Sync processes and try Again. I've tried to close all running instances of bittorrent sync, but without success. The same happens on both on an Win XP and Win7 machines I've updated. Any idea?
