Gah! Crashed computer during writing....all was lost!!!

It's been one of those days! I had been writing a very effective dialogue between two people and it was just clicking along. I couldn't get over how well the story was coming along...and then, kaaaapooooowwww! I got the blue screen of death! Lost it all...sigh! Trying to remember what I typed once again...remember, save early, save often!!!! Gah!
