Hello again,

Unfortunately, changing the number of electrons to 178 per molecule is 
leading to the error:

Any suggestions how to overcome this problem (i.e., how to tell the 
program that we got closed shell system with a charge of +1 per 
molecule)  will be greatly appreciated.

Best regards,
Piotr
