Hello,
I am having trouble uploading a sketch to my new Arbotix board. The same sketch worked on my previous Arbotix board, but it seems that the AVR loader in not communicating with the board (not sure if that is what is actually happening).
I'm using Windows 7 64 bit and am receiving the following error:
avrdude: stk500v2_command(): command failed
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
I have gone through the troubleshooting found here:

but have not been able to find the problem. Any help would be greatly appreciated.
