Greetings Rob,
If you have NI-DAQ 6.9.2 or 6.9.3, then you should have NI-PAL 1.5.6f0 (or higher). The tool attached below should allow us to correct the behavior that you are observing. Most commonly, the commandline "palbase.exe -s 44000000" followed by a reboot will do the trick. If this does not resolve the issue, then I would recommend contacting our email support at http://www.ni.com/ask. I am confident that we will have your software running smoothly within an email or two.
Sincerely,
Jeremiah
