Sequence Lost, Please Help!

Hi all,

Thank you in advance for whatever advice you can give me. While working on a film in FCP7, solely confined to one sequence folder, a multitude of sequence folders were produced; sort of a splintering of the one sequence I initially worked in. I ignored this clutter and continued building my movie in this one sequence. However, the program unexpectedly closed and I was forced to reopen FCP7. Upon doing so, all of the sequences were closed and I had to search for the sequence in my Finder under Autocache Vaults. There were many sequences with different dates and codes on them and my search became more exasperated. Once, I came across a sequence that was close to the final sequence I had saved, but not quite. As each day goes by and I attempt to open these sequences, more sequences are produced in the Autocache Vault. How do I find my last saved sequence, the one which contains the most current work I've done and end this cycle? Thank you!
