Hello, I downloaded the Bittorent Sync yesterday and installed on my machine. I created a sync folder (already has content before). I gave my secret to my friend. He said he successfully got all my files. But today, when I woke up and started the BittorentSync, all of a sudden all my files are gone. Just the files, the folders are still in there. I asked my friend if he deleted the files in the sync folder but said no. I know it has not been deleted, and all my important files are gone. I don't where it goes.
