We represent authors in negotiations and litigation with publishers. As a general matter, when you contract with a vanity press, you may do as you please, provided that you comply with any express restrictions contained in your publishing agreement. Without looking at the agreement, it is not possible to determine whether and on what terms you may simply go elsewhere. In my experience, the difficulties you are having are endemic to vanity presses across the board and are unlikely to change meaningfully if you change publishers. If you'd like to discuss the situation, feel free to give my office a call.
