Hi Taye (and also Steve),
Since the AM1 and UAM1 keywords activate the old code in l402 for
wavefunction and gradient calculation SCF keywords won't help. One
useful trick is using "UHF Int=AM1" insted of UAM1 which will use the
regular SCF code (l502) for the semiempirical calculation. This should
help on its own and also, SCF=QC should work is necessary.
Best wishes,
Odon
