[14] WiFi shield nt present

This is a bit frustrating…
I now have a real Arduino UNO, a real Arduino SD WiFi shield and a XBEE S1.

I am using the official Blynk Arduino WiFi shield sketch.
The sketch compiles just fine but all I get from the serial monitor after uploading the sketch is the following:
[14] WiFi shield not present.

It would really be nice for someone to help me get this working as the web site makes the whole process seem really simple!

PLEASE HELP!
