The second screen shot in your first post is what we need to look at. In particular we need to make sure that the inputs to the AI Config, Clock Config, and AI Start are all correct. Any erroneous inputs to the Config VIs are thrown when you try to start the task. I'm guessing this is what you provided a screen shot of in your last post, but the second image isn't showing up, please repost this if possible.
Another possible fix would be to upgrade to the current driver version (<a href="http://joule.ni.com/nidu/cds/view/p/id/570/lang/en" target="_blank"> 7.4.4 for Traditional NI-DAQ</a>, and, if you like, <a href="http://joule.ni.com/nidu/cds/view/p/id/965" target="_blank"> 8.7.1 for NI-DAQmx</a>--though in this VI it doesn't look like you're using DAQmx). Upgrading the driver would fix this issue if it was a bug that has been fixed, or if your current installation is corrupted for some reason. While this error sounds like it?s probably a configuration parameter issue, if this is the only system you're working with then upgrading the driver wouldn't hurt anything.
Cheers,
