MS-Access and CLI/I-NET

I've searched the USENET archives and haven't found the answer to this particular problem -- I'll appreciate any help you can give me. We're trying to attach Informix tables to an otherwise empty MS-Access v2.0 database. We're able to attach views and tables without primary keys. When we try to attach a table that has a primary key, Access give us a message "owner_tablename is not a valid name" where owner is the owner of the table and tablename is the table name. Unfortunately, I don't have the exact version numbers here, but we're on 7.11 of Informix and the latest CLI/I-NET (we just purchased and received it). Thanks for any help you can offer, M.
