NFC Shield - "Didn't find PN53x board"


I just received my NFC shield along with a brand new Arduino Uno R3 today, and have been trying to get the examples running.
At first the examples wouldn’t even build giving errors in the PN532.h header file, so I found a different library on github that is Arduino 1.0+ compatible.
Now when I run the example it just says:

Didn’t find PN53x board

Very annoying.

I have simply plugged the shield into the Arduino board, no jumpers or mods anywhere.
What am I doing wrong?

Thanks in advance.

hi, the Seeed NFC shield Lib has been upgrade to support arduino IDE 1.0+ , please download at:
as your problem"Didn’t find PN53x board" , as we don’t know the firmware you are using , i can estimate the causes.
thanks for your understanding.
