All meters disappear !

Hello,

For two days and no particular reason, the meters do not work anymore. Whether in the mix console or in the Project window. Only the meters operate midi tracks.
This problem he already met? It’s rather urgent I can not mix without the meters.

I’m on PC, Windows 8.1, Cubase 7.0.7 with two screens with a 32-inch touchscreen.

Thank you.

EDIT: The problem occurs on both 32 and 64 bits.

Up, please

Bumps the word.
So, you have no movement in the midi or audio meters?

Only on instruments and audio tracks, midi works.
