Need help with the AD8230

Question

I can't get this device to work. 
 I have built it exactly as is in the data sheet. 
 I am using a thermocouple K as input sensor. Gain = 100, RF = 100k, RG = 2k (I also tried with 10k & 200) 
 The output is approx zero. 
 I have added an output offset as described in the data sheet (300mV). 
 Vout = +5V, Vpin 7 = 300mV. I have replaced RT7 & RT14 with 10M resistors. (Bias current path) 
 see attached schematic 
 I have 6 boards behaving the same way 
 Any suggestions? 
 the eval board is obsolete, so I can't buy it to try 
 thank you
