Using NI-9402 I2C with CRIO-9039

Hi, I'm currently trying to use the NI-9402 I2C with CRIO-9039.  It works fine in Labview  but everytime I make changes to it, I have to go through a 5 minutes of Synthesizing (see attachment). Why does it do this? Can this Synthesis be bypassed?

Also, when I tried to add this VI to Teststand, it gives me an error (see second attachment).  Any idea how to get this VI to work in Teststand as well?

This is the Labview VI I am using: http://sine.ni.com/nips/cds/view/p/lang/en/nid/210637 

Thanks.
