Hello Mike,
I am suspecting that you are having a Windows permissions problem, and there are a couple of things that you can do to help and determine what the problem might be. First off, are you logged in as an administrator or as a user that is within the administrative group? If not, then please try to obtain the proper permissions so that Windows doesn't restrict what you can access and modify.
If that doesn't help any, then you should try a reinstallation of the driver. It sounds like you went about the correct installation procedure the first time, but something could have gone wrong that we are not aware of. First remove your hardware from Device Manager, and then uninstall NI-DAQ from Add/Remove Programs. Once done, shut down and remove the hardware, a
nd then reinstall. I think you know the procedure well enough, so I'll leave that there.
If the problem is still persisting, please post back with a little more information - what version of the driver, LabVIEW evaluation version, Windows Service Pack installed. It would be nice if you could even try and determine whether or not it is the hardware causing this problem, although I don't highly suspect it, by trying another plug-and-play PCI device - another NI board preferably. Also make sure that there are no conflicts with other devices which might already be installed and showing in Device Manager. If you have anti-virus software running, I also recommend disabling it during your troubleshooting experience as this type of software has caused multiple problems in the past.
I hope that things are working better for you sometime soon. Keep us up to date on your steps.
