Adobe added some significant features this week with Photoshop Lightroom 1.1, but some people are having trouble upgrading from version 1.0.
Adobe is trying to figure out the causes for problems some have had moving their database of photos and editing changes from 1.0 to 1.1. "We're very concerned about database upgrade issues," said Adobe's Mark Hamburg on the company's Lightroom forum.
Hamburg's advice includes running Lightroom database integrity checks often; if your computer crashes, don't delete the "journal" file that records database changes; and don't open Lightroom's database with other tools. (Lightroom uses the open-source SQLite database software.)
