Yeah, there are some similarities between your app and the one described in the first 3 msgs of this thread. But also some differences. The reconfig needed by that app had to do with the differences and your app should be able to simply stop and start again.
FWIW, there's another thing you can do to make the stop and restart process just a little more efficient. It isn't really needed in most apps, but might be worth knowing about for the future. It involves explicitly "committing" the task 1 time before the first time you start it. Here's an example with some benchmark speed info. For more info, you can search on the "DAQmx Task State Model."

CAUTION! New LabVIEW adopters -- it's too late for me, but you *can* save yourself. The new subscription policy for LabVIEW puts NI's hand in your wallet for the rest of your working life. Are you sure you're *that* dedicated to LabVIEW? (Summary of my reasons in this post, part of a voluminous thread of mostly complaints starting here).
