Hello,  
I am trying to use Slicer with the Plus Server connected so that I can use the transforms function for the Ultrasound images. However, I am getting the error show in the image. I have installed all four SlicerIGT related extensions in Slicer but I’m not sure what’s causing this error.

The error says:  
|ERROR|022.003000| Cannot connect to the server (127.0.0.1:18946).| in E:\D\PSNP64b\PlusLib\src\PlusDataCollection\OpenIGTLink\vtkPlusOpenIGTLinkDevice.cxx(152)  
|ERROR|022.311000| Socket error in device TrackerDevice: failed to receive OpenIGTLink transforms. Attempt to reconnect.| in E:\D\PSNP64b\PlusLib\src\PlusDataCollection\OpenIGTLink\vtkPlusOpenIGTLinkDevice.cxx(241)

Your Plus configuration file seems to be incorrect. You can get help on writing configuration files for Plus by submitting your question as an issue at PlusLib repository’s tracker ([https://github.com/PlusToolkit/PlusLib/issues/new](https://github.com/PlusToolkit/PlusLib/issues/new)).
