CUE refuse to start

Hey guys.

I was really happy 2 hours ago when i came back with my brand new k95 rgb mx red (azerty).

So I unboxed it, i looked the manual and i launched the Corsair Utility Engine (CUE) Software v1.3.91 installation.

Then i used 1 usb 3.0 (keyboard logo) and hurray, my keyboard was working !

But then i heard the "unplugged usb" sound.

The CUE icon was still on my windows bar but when i moved my mouse (roccat tyon) on it it disappeared.



I tried relaunch it manually, i lost focus on my firefox and directly got it back. The icon is here but still when i move my mouse on it, disappear.



I tried uninstall/reinstall, i tried usb 2.0 (arrows first, keyboard after) but nothing better, still the same issues.



When i launch CUE it seems to "do something", really fast, and then disappear.

I was hoping to configure macros/profile/colors...



Can someone help me please ? i am running Win8.1.





Thanks guys..
