Error 200279 - DAQ Assistant - Continuous Samples

[MrOliver2]

Hello,
I am having problems with NiDAQmx 8.6.1.
 
OS:  Windows XP Home
LabVIEW 8.0 Student Edition
 
I rebuilt my computer (new CPU, MB, Video, Memory, etc) 9Jan2008 and everything (including LabVIEW) worked fine.
 
I tried writing a simple program using the DAQ Assitant and error 200279 popped up.  I isolated it to the DAQ Assistant. 
 
Using Acquisition Mode: N Samples, Samples to Read: 100 and Rate (Hz): 1K, the Test Panel runs as it is supposed to.
 

Using Acquisition Mode: Continuous Samples, Samples to Read: 100 and Rate (Hz): 1K, the Test Panel returns Error 200279 and DAQ Assistant hangs up and even using Windows Task Manager takes a couple of minutes to shut it down (CPU Usage stays at about 50%).  Changing the Samples to Read to 2 gives the same result.
 
I called a friend who was also using NiDAQmx 8.6.1 and she did not have this problem at all.
 
So the problem is related to my computer system and NiDAQ.  Any idea on how to solve?  Screen shots attached.

Hello Matthew,
Thanks for the response.
First off, yes I did try the "Run Button" in the DAQ Assistant, but it also had the same result- Error 200279 appeared and the system hung.&nbsp; The settings were Continuous Samples 100 Samples and 1KHz sample rate.&nbsp; Even when I dropped the Samples to 5 (five) the error still occurred.
From "Find Examples" I tried Cont Acq&amp;Graph Voltage-Analog SW Trigger.vi, but the VI just hung up and the CPU Usage (from Windows Task Manager) remained at about 50% even after I ended the process for several minutes.
Any other ideas?&nbsp; I appreciate the help.&nbsp; I have attached another screen shot.

Hello Matthew,
I did the following from your recommendations.
&nbsp;
&nbsp;&nbsp; 1. Right clicked&nbsp;my device in NI-DAQmx Devices&nbsp;&nbsp; 2. Selected Test Panels&nbsp;&nbsp; 3. Selected Mode=Continous&nbsp;&nbsp; 4. Clicked Start&nbsp;&nbsp; 5. DAQ gave the error 200279.&nbsp; So there was a Driver/Hardware/Computer problem.
&nbsp;
I uninstalled and then reinstalled NI DAQmx 8.6.1 and repeated the above.&nbsp; The problem disappeared.&nbsp; So the root cause of the error was a poor software install.
&nbsp;
Thanks for your help,
