hi,everyone!  
this is my code:

NetworkScanner ns = new NetworkScanner();  
ns.Scan();  
ControllerInfo ci = ns.GetControllers();  
Controller controller = ControllerFactory.CreateFrom(ci[0]);  
controller.Logon(UserInfo.DefaultUser);  
Console.WriteLine(controller.SystemName);

Task ts = controller.Rapid.GetTasks();  
using (Mastership m = Mastership.Request(controller.Rapid))  
{  
bool bb = controller.AuthenticationSystem.CheckDemandGrant(Grant.ExecuteRapid);  
ts[0].LoadProgramFromFile(controller.FileSystem.RemoteDirectory + “/THIS/THIS.pgf”,RapidLoadMode.Replace);  
ts[0].Start();  
Console.ReadKey();  
}

these code works well if i reference them from the PC SDK 5.15. The virtual robot in RobotStudio will run the “THIS.pgf” when i run these code. But, when i reference them from PC SDK 5.60, the virtual controller will load “THIS.pgf”, but virtual robot don’t move. the value of “bb” is true during my test.  
 ![]()  
the pictures is output when i test the code with PC SDK 5.60.  
Can someone help me?  
Thank you!
