System Browser Missing

[Anonymous]

I am a new user and traying to preform and energy analysis on a model. However, I cannot add anything to my system zones as I do not have access to the system browser:

F9 does not work either.

What am I doing wrong? How do I get the system browser to display?

Thanks

Are you using LT?

1. If you have Revit full options then go to Options >User Interface > check all three System Tabs for MEP
2. If you have Revit LT then you have no MEP available

Yes using full version @RobDraw 

Thank you @constantin.stroescu  for you answer and detailed help. Really appreciate it.  That has fixed it.

If Rob Draw's solution doesn't work and you are using multiple monitors, unplug the 2nd and subsequent monitors.  I had this problem after undocking the System Browser.  It didn't re-appear until I unplugged one of my two monitors.
