Error -200874

[labviewmission]

Hi ,

I am getting this error all of a sudden in a normally okay running program.

"Error -200874 occurred at DAQmx Write (Counter Time 1Chan 1Samp).vi

Possible reason(s):

DAQmx Write is supported for counter output channels only while the task is running.

To use DAQmx Write with the given task, invoke DAQmx Start prior to DAQmx Write.  To specify the low and/or high time while the task is not running, set DAQmx properties instead of invoking DAQmx Write.

Task Name: _unnamedTask<4>"

I am using the" autostart task"  functionality of the DAQmx .

But it started giving error .

Any help would be highly appreciated.

Regards
