Error: scil_DataP2()-ERR_SC_DATREAD_HDR

Wow. The last time I have any record of this error is from 2016!  The Smart Card was replaced but the error happened again later.  The computer was imaged and MassHunter reloaded, reconfigured, and the problem did not reappear, or at least I was not contacted about it further.

I would suggest that is the safest option. Reimage the PC using the Agilent image that came with the instrument controller computer, reload and reconfigure MassHunter. Try again.

If the error persists, try reflashing the firmware in the MS.  The worry is that if the SmarCard is the problem that trying to reflash the firmware first may cause the board to be unusable and require replacement.  If the PC work doesn't fix it, the SmartCard in the MSD would be next.
