I hate to say it, but as far as I have been able to ascertain, unless you were rendering your animation as a bitmap seq. file you are SOL. I've had power interruptions abort long animation renders on more than one occasion, but seq. files are still salvagable even if they are interrupted because the individual .bmp files are stored in a folder. It is easy to convert the seq. files to AVI or QT in a video editing app. Maybe Clay will chime in on this, he's one of the experts.
