witilt configuration menu missing

Hi,

I bought a witilt recently. I charge it using a 5V 1.5 A adapter. Everything works fine for some time until yesterday. I cannot open the configuration menu again although i manage to pair witilt using bluetooth. The light that indicates bluetooth is still on but the other light in the middle is off. What is the problem? is it the charger? Please help me…PLEASE>>>URGENT

seems like the witilt cannot provide the menu again…
