Reusing hiberation file?

I’m trying to find a way to reload, or reuse a hiberation file, using WinXP SP2.
I was working on a large project and ended the night by hibernating. This morning, I started up from hibernation and started working on the same project. My system crashed, losing about 12 hours total of work. I had to reboot, but now I’ve lost all that time and work. Is there a way to reload the hibernation file and get back the system as it was when last night and only be out the few hours that I put in this morning? Great thanks for any help.
