how to control vna via agilent usb-gpib interface

[peanuts]

hello Labviewers,

I'm trying to control a vector network analyzer (at8722ES) using the agilent USB-GPIB interface 82357a and Labview 7.
But the devices and the software don't communicate with each other. I've read carefully through these postings:

I downloaded the vi from the given link, but had no success controlling my vna. Can't I use these vi with my USB-GPIB interface?

I would be grateful for any hints how to make the three systems work together.

thanks in advance
Simon
