Upgraded to Lightroom 4.0 from 3.0. Do not have my plug ins, User Presets in Printer and Develop modules when bringing in my previous catalog. Why? Why weren't all my settings, preferences, plug ins etc etc copied with the upgrade? This is a horrible upgrade solution. I talked live with customer support. They said, call us back in a few days! WHAT! I paid $79 for a product with know n bugs?!!
