No bootloader found ! Is there no hope for my XBEE pro S1?

I have 2 XBEE pro S1 , one is connected to the arduino uno, the xbees were configured properly and have been working well for over the past 2 months but suddenly the one connected to the arduino has stopped working , I’m using a 3.3v regulator on the xbee and a 2k, 1k voltage divider between arduino and xbee Din , the dout is connected directly to the arduino.All of a sudden the Xbee stops transmitting. I’ve no clue what the mistake I made. I tried the recovery options and it shows no bootloader found , the ASSO pin of the XBEE USB ADAPTER doesnt flash.
I’ve a competition to take part in tomorrow please help me out .

Looks like you need to order a new module. You also need to have a voltage divider between DOut and the Arduino otherwise you are still connecting the 3V XBee to a 5V device.
