Hi all, I got an MT1C a few weeks ago and was fairly happy with it, but today when I went to turn it on I noticed it won't switch modes anymore when I twist the head, it just switches off. In a addition I can't scroll through modes while the head is twisted. The light is basically either on turbo or off. Anyone experience a problem like this before? Kind of disappointing if the light is already malfunctioning, as I didn't even use it for anything, it's just been sitting on my shelf since I bought it.
