Problem importing photos. After pressing "Import" button Lightroom shows the message - "An internal error has occurred. Recursive load attempt for namespace: ImportCommonUI" Maybe somebody has any idea to solve?
This is a symptom that you have a corrupt or incomplete Lightroom installation. I would suggest you uninstall Lightroom and delete the Lightroom application folder (this makes sure that you starts with a known system state) and reinstall Lightroom.
