an urgent problem of Cadence Virtuoso while converting CDB to OA form

Recently I am trying to install CSMC35 library in Cadence Virtuoso. All the steps are finished except for converting them into OA form. The tips for the problem are as the picture shows:

I am waiting for your answer or suggestions.

This problem has been solved.
The tip means that I can`t convert the CDB files in the same directory as the 'cds.lib', so I copied the CDB files to a new place and established a new 'cds.lib' in which I printed a new CDB-file-directory. Then repeat the normal steps. That`s OK.
