Mystique – column width too large

I accidentally (aaagh this mouse is rubbish) clicked on the ‘reset to dafaults’ button in Mystique settings. I am now trying to get the blog back to the layout it was before! My blog is http://www.globalsurfadventures.co.uk The post column is too wide now.

The sliding column post width bar is not working. It was working before, and the single column style worked fine too. I was using IE on my friends computer, but now using MozillaFF. So I can’t correct the column width which has gone too wide and pushed the single left hand column out. I had all my widgets and links there.

I tried to use the suggestion about adding some user css and ‘fluid’ style, but this did not work. Please help as my blog looks awful!
