If you have a backup of the hard disk, you will need to restore it. Then you can export the private key used by the Recovery Agent.

If you do not have a backup of the disk, there may be some hard disk data retrieval companies that can recover the information, but I would not hold out hope.

Information that you will need is located here:

If you cannot backup the decode keys, try installing a fat formatted HD and copying the files over - since fat does not support encryption, this MAY disable it - however it may fail or you will get unusable data if the OS cannot properly decode the files.

Luck,
