metronom click missing

in my cubase 6.5 recently i have seen metronom click are missing during recording and playing, please help ?

Check your VST Connections. Make sure “click” is enabled on your output.

Also, if appropiate: check Control Room if click is enabled.

thanks for suggestion, metronom click missing sometimes not all time,sometimes 1st click or 2nd or 3rd or 4th click going off.
