energy ROM cannot be backed up by Sprite Backup

[cfong]

I am using the latest July 4th version Energy ROM 29022 build Sense 2.5 cookie 2.0. It doesn't seem to work with Sprite Backup. After the ROM is loaded and running, I immediately ran the Sprite Backup, but was told the backup failed, system files couldn't be backed up.

I used the Jun 11 version, same result.

Am I alone on this?
