ITunes could not restore the iphone because the backup session failed error

I'm trying to restore a backup onto my iPhone 5 that I have saved, and is currently in my 'backup' file in my itunes folder. I currently updated to the iOS 6.1 version and have completed a full factory restore of the system. Now I want to restore from the backup I saved earlier which I know still exists because when I click to manually restore backup, it gives me the option of the backup that I saved. However, an error occurs saying, "iTunes could not restore the iphone because the backup session failed." I have checked countless forums and have tried the following (I'm running on windows7)
Running itunes as administrator, changing my timezone, turning off my firewalls, saving the backup onto another account, resetting the iphone, restarting the iphone and computer, killed the application 'AppleMobileBackup.exe'.
Each solution has not worked for me and I would really like to get my backup that I saved onto my phone again.

Here is a helpful article: http://www.iphonebackupextractor.com/blog/2012/oct/16/upgrade-iOS6-backup-safely-prevent-data-loss/. If restore from backup errors, I would recommend you to use the iPhone Backup Extractor to extract data off the backup and import it back to phone afterwards
