Hi,

I followed the tutorial A1 (advanced version) by Dr. Ross Walker for my
molecule. I was getting stuck in RESP step to calculate the atomic charges.
I got errors as *" Error termination via Lnk1e in
/usr/local/g03-userred/l301.exe at Wed Oct 20 12:39:25 2010.
 Job cpu time: 0 days 0 hours 0 minutes 2.3 seconds."

This is my p2n file (RED server job number was P540) as below:

REMARK TITLE HIZ-ndm
REMARK CHARGE-VALUE 0
REMARK MULTIPLICITY-VALUE 1
REMARK

Could you please help me? What was the problem caused?

Thank you.
