Hi , 

I am trying the simulation tutorial for the simple simulate robot. When I run the empty project(black screen) and try to to open the EntityUI manifest as it is said in the tutorial , after a while nothing happen , I get an error  "Partner enumeration failure : SimulationEngine " 

But when I open the project from /sample/simulation tutorial/Simple robot with drive it works properly . Also i tried another manifest at it worked. 

Anyone knows what is the problem ? is that EntityUI manifest problem ? if so , how should i solve it?

btw, I am using RDS 4 .

Thanks.
