Error when loading data in ASO - multiple rules_file

Hi,

When using the following MaxL statement:

import database 'GMI_318'.'GMI_VEP' data
   connect as admin identified by 'password'
   using multiple rules_file 'lf_curr' , 'lf_copa', 'lf_cvol'
   to load_buffer_block starting with buffer_id 100
   on error write to "error.txt";

I get the following error:

lf_curr', 'lf_copa','lf_cvol' does not exist

These rules files are on the server, we've been using them for a couple of years now.  Nothing in the logs.

Any ideas?

Thanks,

Valerie
