  • If you have no history states, what do you anticipate the history brush doing?

Actions such as cropping, trimming, using the Image Size or Canvas Size commands, or rotating any amount other than 180 degrees can prevent you from going back to a previous state and will give you this error message.

I would suggest using the tool first and then making further changes.
