Recovering lost library?? Please help!

Hi!

I've been working on a film for the last two years and have recently had a massive set back! Both my main external hard drive and the backup hard drive failed, resulting in me losing most of my work. I still have all of the original footage, but the final cut library has gone. I found a folder of autosaved final cut backups on my computer, and I was wondering if there is a way that I can use this with the original media to piece my film back together? At the moment when I open up the backup file it says that the library can not be found as it is no longer "in its original location" (since it has been lost). Any advice would be hugely appreciated!!

Thanks!
