You have to use a tool to repair the bkf file.
I was also suffering from my BKF file corruption. In these back files there was lot of important data in it. Its create lot of tension to recover my corrupt BKF file.
After reading on web world i came to know that BKF file can be corrupt due to lots of reason, they are:  Virus attacks, CRC errors, The backup file is unusable,  Improper shutdown,  Backup interruptions, Unrecognized media. Maybe due to any of these reason my BKF file got corrupt. I also get a perfect solution for this. This is a "SysInfoTools MS BKF Repair" tool. Its a third party tool which is very effective.
