Kaira Pro Firmware Update Freeze

Hi all,

I think my initial firmware update of my newly purchased Kaira Pro froze. Let my try to describe how the screen looks since I can't seem to upload pictures here.

Top of the screen: connect the headset to the PC using the USB charger cable
Middle of the screen: Please don't power off your computer or unplug your device(s)

Updating 1/2751... 100%
The green loading bar is full.

Bottom of the screen (left):
Firmware version: 0.00.00
Lates version: 1.00.12

Bottom of the screen (right):
Cancel & Update (nothing happens if I click on them).


Is it safe to unplug the headset and start the update again or how should I proceed?

Thanks for your help.

[edit] Found the upload function eventually, so you can also see the screen in attached picture.
