Is this an oral or written agreement and what documents do you have that pertain to your case? I'm licensed in California although it sounds like you have a statute of limitations and a statute of frauds issue in your case. My suggestion: hire a lawyer who can advise you of your legal rights in your state. An exact answer would require a review of the facts of your case and review of your doucments and case history.
It all depends on whether you executed an oral or written agreement regarding the "deal." Written agreements are generally more enforceable than oral agreements. However, there may be a solution based on one or more exceptions to the Statute of Frauds even if it was an oral agreement.
