Okay so I've had my MagicJack for about two weeks now and it has been working fine, and all the sudden it cut off in the middle of call and when I try to use the phone it shows up as unavailable the way it does if it isnt hooked up to anything at all. I don't understand why it isnt working now, when it was working perfectly fine before. Does anyone know what is wrong with it and how to fix it?
