hallo,

there is a problem with my robotstudio.  
@ the time I open an existing robotstation with a robot in,  
the Virtual controller tries to start up , but I get the error:

RobotStudio .NET exception: No response from controller.

============================================

Base exception: RobApiException

No response from controller.

after this error robotstudio blocks.

I have this problem on all my existing stations.

the same problem I have at the time I want to add a brand new created controller to a robotstation.

trying to solve the problem I was already uninstalling and installing back robotstudio (5.15.02) but the problem was still persisting

afterwards I was installing version 5.60 but also with this version the problem persist .

does anybody has any idee about what is wrong?

thanks,

bart
