I was attempting to run a single point calulation using MP2/aug-cc-pvtz. When 
I first tried counterpoise=2 for these calulations, there were problems with 
disk space, so I separated the BSSE calculation into the 5 parts. The first 
part, with just the single point on the entire system, worked for all of the 
complexes, but when used the same procedure with the Bq and added in the basis 
set (MP2/gen and then at the end of the com file I placed the basis set from 
the .log file from the first part), there seems to be the error that is stated 
below...
