Just updated my Windows 7 Client to 8.16.8.
This version cannot display video from any camera. Watermarks are gone. Every camera window is blank.
The Client log file (p2pc_mem.txt) has the same fail entry for each camera:
Q fail:r=-3,h=0,c=0.5.11.16 'h' is the camera number. What do the 'r' and 'c' numbers indicate?

Have to go back to a previous version
