Single Supply operation for AD736

Hi

I found the application note AN-268 regarding the RMS to DC converters. IN that i found a circuit that allows for single supply operation of the AD736 (Figure 12 in the application note). However when i try to simulate the circuit, it does not work and the output goes all over the place. I had earlier also tried using the TLE2426 - Virtual ground, but i understand that it has a limitation of very low sink current of max upto 30mA hence looking for alternatives.

 

I have attached my circuit below. Any ideas of what i am doing wrong.
