Friends, Recently I have installed 16 cameras, however I am facing a big problem trying to use (pressing F10) the Viewlog, when I try to view recorded images the screen turns blue and just can't see anything. The play button is disabled This function, I'm trying to run inside the machine which I have installed GV-800. Software Version: GV800 V.8.02 What should I do to fix this problem? Did I realize some setting wrong? I appreciate the attention, Baltom
