Hello Seth,
Thank you for contacting National Instruments.
What exactly do you mean when you say that your GPIB card is not working? Is it still showing up in Measurement and Automation Explorer (MAX)? Is it showing up in your Device Manager? If you can see it in MAX, what happens when you try to open a VISA Session? Can you communicate or does it time out?
Please respond with more info and I will be glad to help you out.
