When I flash back the demo, it works perfectly. Programs transferred with the Arduino IDE also work, only UIFlow 2 doesn't.

Hi everyone, I flashed UIFlow 2.3.7 onto my Tab 5 using mburner. Afterwards, it starts up and the backlight is on. I can also access it from UIFlow via USB and Wi-Fi. However, it doesn't launch any programs after the successful transfer. What could be the problem? Nothing seems to be happening on the Tab 5. Thanks, Thomas
