FIO w/ XBEE won't reset or upload new programs

I get the following error when uploading to my FIO: avrdude: stk500_getsync(): not in sync: resp=0x00

It is a problem that has gotten worse over time, and now won't go away. The rss light on the shield continually blinks, on for 5 sec and off for 1.

The radios are still communicating because the Serial.println text from the previous program continues to feed through the serial monitor. When booting the lights on the shield and FIO turn on/flicker but then stop on the shield and the RSSI blinks on and off.

Anybody have a solution or explanation?

Hello khansen3,

Have you tried to upload a new program in your Fio, without the Xbee and using the USB cable?
