Hi Ross,
Thank you so much for your response!

I also had this "not enough memory" error at first, but adding the
-bmaxdata:0x80000000 flag to xlf90 made it go away (which is a bit
strange, because by default executables should be able to use up to
256MB on our system).

I will follow your suggestion and delete the sander.QMMM executable
from the exe directory.

Thank you again!
