[VoroshylovDmitry]

When I run command -> "qvh activate" in first time I have this one errors:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x10 pc=0x529626]

If I run it again every thing is ok and I see devece data:

{"device_activated": 
{"deviceName":"iPhone","screen_mirroring_enabled":true,"udid":"divece_id","usb_device_info":"vid=05ac,pid=12a8,bus=3,addr=11"}
}

Do I have an error in the software setup?
