Error -89137 for AO when also doing synchronized AI

[Chris_12345]

My equipment is a PXIe-1075 chassis populated with a PXIe-8130 controller and several PXIe-6259 cards, running LabVIEW 8.5 with Windows XP Pro.  I am trying to acquire synchronized analog voltage data from the ai lines, and this is working great.  However, meanwhile I am also trying to set the voltage of an ao line, and am getting an Error -89137.

I am using the example code "Multi-Device Synch-Analog Input-Cont Acquisition.vi".  When I select some Physical Channels and set the Synchronization Type to "M Series (PXI)" and run it, I get Error -89125, so I  have modified it slightly, where the "Get Terminal Name with Device Prefix.vi" has been replaced with "DAQmx Export Signal (Most Signals).vi" and wired with "Start Trigger">signal and "PXI1Slot2/PXI_Trig0">output terminal.  I have also changed "DAQmx Start Trigger (Digital Edge).vi" to be wired with "PXI1Slot2/PXI_Trig0">source.  See attached VI.  Running this slightly modified code works great, no problems.

While that code is running, I now also run the example code "Gen Voltage Update.vi".  When I do this, I get Error -89137.  How do I avoid this error?

Thank you for any assistance you can offer.

NI helped me to resolve this issue.  See attached VI that resolves the problem.

I have labview 8.2 and have the same problem. Can you post screenshots of your code Test.vi so I can look at it? I can't open Labview 8.5 codes. 

thanks!

Here is a screenshot. Unfortunately I only have access to LV2011. A number of VIs that came with LV85 have changed names or are no longer available, hence the missing icons. I've labeled the missing ones in the screenshot. Hope it helps.
