NI MAX not communicating with GPIB instrument

[Paul_Knight_Lockheed_Mart]

I have an issue with MAX.    I have hooked multiple instruments to a GPIB -USB-HS.  When I open MAX and go into Devices and Interface, I see the GPIB-USB-HS, but I don't get the "Scan for Instruments" or the "Interactive Control".  ALL the instruments are there at the proper address, but when I click on them, I don't get the "Communicate with Instrument" or the "Interactive Control".  I only get the Refresh button which does nothing.

I have tried resetting the configuration and I have gone to just a single instrument.  This setup was working a few months ago.

Has anyone seen this before?

I am not using Agilent VISA.  I have MAX 14.5 and a National Instrument GPIB controller.

Have you tried doing a repair of NI-488 and NI-VISA? What versions of those are you using?
