 Dear all,
 I am new to the area of computational chemistry and am beginning to use Gaussian
 09 in my studies of gas-phase ion chemistry in the mass spectrometer.  I am
 attempting to optimise the geometry of the ionic product of a gas-phase
 reaction, using Gaussview 5 as a GUI for Gaussian 09 and the default settings
 for the program.  When I submit the job, I obtain a message saying that the job
 can not run because of severe error 2070.
 Can anybody explain what this error means (I have had a look online and can not
 find anything useful) and how to prevent it from happening?  Happy to share
 further information offline.
 Best wishes,
 Stephen Holman
