Finding lost files

[Artist]

I turned off my computer without saving the changes to my file over the
previous day. When I turned it on again, only the previousl day's saved
version appeared on the list of files. I looked for an autosaved version,
since I know autosaves take place regularly, but I have been unable to find
autosaved or recovered files using an 'everywhere' advanced search.
I have Windows for Business 2007 and Vista. Can you suggest how I can get my
file back, please?

Windows for Business???????????
Auto save, presumably in office, has to be turned on, in whatever component
you were using
