There are three things you can try. First, you can try to take ownership of the folders as the administrator and grant yourself access to the files/folders. Second, you can log on as the administrator and remove the encryption attribute from the folders and set the folder permissions to allow you to access them. Finally, if you were using CA's when the folders were encrypted maybe all you need is recover his EFS keys from the CA's server/backup files or maybe revoke his certificate and give hima new one which will produce a new set of keys that just might work with the restored data if it's still considered his after the restore. Good luck.

SINCE YOUR SID'S USER_ID HAVE CHANGED, PLUS THE CURRENT CERTIFICATE (BOTH, THE NEW AND THE OLD ONE) COULD NOT MADE THE MESSAGE KEY FOR READING THE FILE.
YOU WILL HAVE TO RECREATE YOUR USER NAME WITH THE SAME SID THAT YOU HAVE PREVIOUSLY.
THERE'S SOME INFO RELATED AT THE MS SITE REGARDING THE CREATION OF SID'S ID.
BUT WILL NOT BE AN EASY TASK...

HOPE IT HELPS!...
