I lost power on a 65m scene and had the same problem. I was unable to resolve it with Bryce. Fortunately, I had a backup of the file on another drive. Didn't need to use it though because Win ME picked up another problem after an hour of messing with Bryce and set my system restore, which brought back the file. Odd thing is that the 65m file, while it was crashing Bryce after the power failure, was reporting as 0 megs in the file manager. If your file is reporting 0 size, then its gone and you'll have to find another way to restore it. Look in the Bryce temp file and see if there's a backup there.
