spin-orbit coupling problem whith gaussian

	Dear all,
 I have a problem with g94/98. I want to calculate the spin-orbit
 coupling for a cluster consisting of one Cu and 6 O atoms. The
 calculation stops after a few seconds with the error message:
 (Enter /app/physik/cap/cqcp/gaussian94/g94/l319.exe)
 No effective charge available for atomic number  29.
 Error termination via Lnk1e in /app/physik/cap/cqcp/gaussian94/g94/l319.exe.
 Is there a workaround to this problem ?
 Thank's in advance for any help.
