Mike,

Try using RealBand to open your Band-in-a-Box file. Once the file loads save the file under a new name but keep the same file suffix (SGU or MGU). You may find once the file is used and saved by another program the file works. Sometimes opening a file with a different program will have the side effect of repairing the file. RealBand can open files with both the SGU or MGU file suffix.
