NIGHTHAWK M1 - Data usage display

Hello,

My M1 works fine but there is a small rock in my shoe.

You know on the front of the device there are two digital gauge.

One for the battery and another one on the right for the data usage.

Well the battery one works fine, but the data usage doesn't work at all.

I do have the blue light on the top right corner blinking when connected but not the gauge.

Any clue how to re-activate this? 

It worked in the beginning.

Merci

Mitch
