for me it looks like sometimes you forget to evaluate the cell that
contains:
<<NumericalMath`ListIntegrate`
Make sure you evaluate it every time you start a new session (you might want
to make the cell an initialization cell so you don't forget to). To confirm
this guess evaluate:
Context[ListIntegrate]
when when ListIntegrate does not work. If you see Global` as output instead
of NumericalMath`ListIntegrate` my guess is right and you will need to:
Remove[ListIntegrate]
and load the package:
<<NumericalMath`ListIntegrate`
