C6 and VEPro issue

I have Nuendo 4 and Cubase 6 on main Win7 18GB. VE Pro running on 2 slaves as well as main computer. Nuendo 4 sees all instances of VE Pro across all computers. However… C6 does not. It sees nothing but whatever I run on main PC.

Am I missing something? ALL software is current.

Thanks,
Brad
