Hello,
Is this a National Instrument card? Does it have a specific version of driver that needs to be installed specific to your operating system? Is it compatible to the version of labview you are using?
How are you calling the card in your VI? Are you calling it through specific dlls?
Was the card supplied with a specific instrument driver? At what point of time does labview crash? Are you accessing the card at that point of time?
These answers would help me assist you further.
Good luck and have a great day!
