Resource Conflict error

Hi

I am using LabWindows to remote-contorl the CMW 500.

I am using WCDMA Drive from the R&S to run CMW 500.

When I am turn Multi Evaluation mode to see the result of test.

it keeps displaying "Resource Conflict"

I am not really sure about reasons that I am getting "Resource Conflict"

I do not believe that I put wrong inputs...( or i am calling the extra function by LabWindows to control the CMW 500?)

is there any possiable reason that I made mistake in LabWindows ?

thanks
