I've tried creating a similar list of channels, and it seems to work fine. What digital I/O device are you using? I tried it by simulating a PCI-6509, which has 96 digital I/O lines. I'm also using version 8.1 of the NI-DAQmx driver. Here's a screenshot of the code I created, which runs without error for me. What setting do you have for 'line grouping' in the DAQmx Create Channel VI? Also, what error code and error description do you get with that list of channels? Maybe you could attach a snipet of code that shows the error your seeing.
