Hi, MacRumors n00b here, first thread and all. Anyway, I wanted to change my 'short name' on my iMac and to do this I needed to (I think) enable the root user. I logged into the root user and when finished I logged back into my main account, only to find that everything had been reset, including the dock, wallpaper, iTunes, Aperture etc. I do have all my applications, but I've lost all my files and I haven't backed up... Is there something I can do to recover my old user preferences? Thanks in advance.
