I have an Acer Aspire one with Linpus Linux. While trying to install VLC to run AVi video files (unsuccesfully) I seem to have 'disabled' the Nautilus file manager. Is this possible? When I click on my docs or My Music nothing happens. What have I done wrong? Is there any command I can enter into the terminal to fix this? I'm a linux newbie so I need step-by step commands.
