PCI6025e error -200016 occurred at DAQmx write

I am trying to output a 200 Hz sine wave using a PCI 6025e daq card.  I used the express vi's to write a simple program to do this, but then get the following error after the vi has run for a few seconds: "Error -200016 occurred at DAQmx write.  Measurements: Onboard device memory underflow. Because of system and/or bus-bandwidth limitations, the driver could not write data to the device fast enough to keep up with the device output rate."  I have tried changing the sampling rate and number of samplings but have not had any success.  Does anybody have an idea how to solve this problem?  The vi in question is attached.

Thanks

Andre

Andre,
 
Thank you for posting on NI Forums! I tried to run the program that you posted but I was not able to get the program to throw an error. I would recommend trying one of the shipping examples that comes with LabVIEW. If you open up the Example Finder in LabVIEW (Help>>Find Examples). This will open up the Example Finder. In the middle of the example finder you can go through the file structure to find the desired program. Under Hardware Input and Output >> DAQmx >> Analog Generation >> Voltage >> Cont Gen Voltage Wfm - Int Clk program which will be able to produce a 200 Hz's sine wave for you. Hope this helps.
