If you didn't make a copy of your certificates (and no other recovery agent certificates exist),
you won't be able to use your encrypted files. No back door exists, nor is there any practical
way to hack these files. (If there were, it wouldn't be very good encryption.)

Without a backup of the original Encryption Certificate Key, encrypted files
are unrecoverable as they will stay encrypted forever. There is no recovery
method since the encryption algorithm is now completely different with a
reinstall of Windows XP.
