E(VDW) is huge and EGB isn't even a real number. So at least two atoms
seem to be much too close. There doesn't seem to be a bond between them
(otherwise E(BOND) would also be quite huge). Besides, one of them seems
to be neutral (otherwise I'd expect EEL to be enormous, too).
I'd
1) have a look at the structure (using VMD or a similar program).
2) try and minimize the structure with "diel=r", i.e. without GB and see
what happens.
God luck
Andreas
