Don't panic. Do you have a spare drive you could install windows to? If yes unplug your current drive and plug the spare drive in instead. Install windows then plug your old drive in as a slave drive then boot the pc and install easy recovery pro, do a raw scan of the old drive which should now be the secondary drive. Hopefully you'll have a pile of files to wade through which will include the files you need.
Remember you can recover files from pc's that have had windows installed over the old info.
Are you based in the north at all, I'd be happy to help, we women need to stick together
.
BTW I always Ghost a drive before trying to recover data, this way you can always revwert back to the original state and try again.
