[kftvonline]

well, I had this problem sometime now and I am reporting it since I had the problems many times now. sometimes when I am broadcasting in FME, there will be a time when the it will disconnect and it will go to the Auto-pilot. usually when log in to the studio then it will goes as "Can not connect to channel". I am using FME 2.5 and now usiing a wired laptop.
Please fix this.
