You can rebuild the databases yourself from the original PDB files. See the relevant page in the Modeller wiki: http://salilab.org/modeller/wiki/Rebuilding_sequence_databases

Alternatively, you can download updates, when available, from our supplemental data file download page, which is linked from that wiki page and from the main 'download & installation' page.
