I launch the app (Android Device) then I get the message "Sorry, wrong procedure, exit now" and it closes, what should I do?

Firstly please try to scan the code in the below picture to download the APP again: 

Or just pls try this APP on this website: http://fir.im/ajuq.

If it still doesn't work, please send us the file in the folder "RunCam Wifi" in the SD card to help us find the problem by email run@runcam.com. Thanks for your cooperation.
