Grrr! I spoke too fast. When I installed Deep Exploration, I used it immediately and every thing worked fine. I could open and convert and save my files. Few days ago, I have converted some lwo files. Today, after I had posted the previous message, I wanted to see, why it did not work for you, opened Deep Exploration, clicked on OPEN and tried FILE--->OPEN.... Nothing! Loaded an existing file from the Favorites, tried to save, Nothing either. I have uninstalled, re-installed, doesn't work. What happend? That's crazy. Guitta
