Problems with the Gadgeteer Cellular radio

I recently bought the cellular radio by seeed studio, at first it was working perfectly, it sent and recieved messages without any problem but it suddenly stopped working. I didn´t change anything and the modem initialized fine, but that´s all it does. I used the reset button and reinstalled the driver but it still doesn´t work.
Does someone has any suggestions about what could had happened?

sorry to hear the moduel stops work. can you sent more details on what happened now? for example, does the module sents anything out via serial when resetting?
