CCL: ERROR IN INITNF

 Sent to CCL by: "Chris  Perry" [christopher.perry2++wits.ac.za]
 Dear all
 I've been trying to do a geometry optimization and frequency calculation on a
 cadmium complex using the Douglas-Kroll-Hess method to account for relativistic
 effects. However, I get the following error message:
  ************************************************
  ** ERROR IN INITNF. NUMBER OF VARIABLES ( 81) **
  **   INCORRECT (SHOULD BE BETWEEN 1 AND 50)   **
  ************************************************
 The root section of my input file looks as follows:
 %Chk=8m_alv4_0a_monomer
 %Mem=6000MB
 %NprocShared=8
 %NprocLinda=1
 #P B3LYP/Gen
 # Opt Pseudo=read
 # Test Int(DKH)
 # Freq
 The error message only appears when I add the Int(DKH) keyword.
 Does this mean that the Douglas-Kroll-Hess calculation is limited to systems
 with 50 or less variables? Is there any way around this problem?
 Thanks in advance
