Problems Viewing the Mix window


I’ve updated to version 8 Elements in the mixer I have the following problems:

I can not see or select the meters. In the settings button the "Meter Birdge " option does not appear , therefore I can not select and view gauges channels

The "M / S / R / W / I … " buttons appear as disabled , but are pressed not work

Info: PC HP i7, RAM 16, WINDOWS 8.1, NVIDA GeForce GT 750 M

I appreciate the help to work with the new version
