This error message means that the DLL called from the LV diagram threw an exception or caused an expection and didn't catch it. On windows this includes most accesses to bad addresses, page faults, etc. Since the VI in question is DAQ, I'd hope this was also caused by the bad RAM, which caused the computer to access an illegal address or something similar. If this is reproducable and isn't a HW issue, see about getting the circumstances to the DAQ support team. Greg McKaskle
