Additional Information
The NI-DAQmx driver can get corrupted for multiple reasons. Error -200088 refers to the software not being able to find the task in the NI MAX database, which can relate to: the database being corrupted, or the drivers are missing. If you changed to another computer and you just installed SignalExpress, it's possible you're missing the NI-DAQmx driver to work with your NI data acquisition devices.
NI introduced DAQExpress and FlexLogger™ for the new generation of Data Acquisition software. It's highly recommended to consider them for future applications.
