R.E.D. should stop with the [FAILED] status if one of the different
steps did not end correctly... "RED.log is absolutely OK" means you
got [FAILED] somewhere at the end of the log file ;-)

In that case, the set of Cartesian coordinates was not optimized by QM.
Consequently, RESP did not fit correctly...

Did you optimize by QM your big molecule ?
"-10" as a total charge ! this is quite particular & interesting...
Sorry, I can not help more if I do not see your data:
If you wish you can send to my personal email your data & I can have a look.
(our email server reject all emails with attached files with .exe or
.com extensions; if you decide to send me Gaussian inputs rename all
the .com files into .com.o)
I can also run the beta version of R.E.D. Server for you if you wish.
(With R.E.D. Server we will provide many new services for force field
library building for new molecules & molecular fragments - all from
q4md-forcefieldtools.org).
regards, Francois
