In Windows 7 SP1, I disabled automatic unlock for my data drive E: temporarily. When I went back later to re-enable the automatic lock for that drive, I got the error "Element Not Found". This happens when using BitLocker Manager or when using the "manage-bde -autounlock -enable E:" command line entry (run as Admin). So each time I re-boot Windows, the drive comes up locked. I can unlock it OK using the Bitlocker password for the drive. However, I would like to be able to re-enable the automatic unlock. Any thoughts?
