How does the statute of limitations work when a debtor moves to another state?

Question Details: I had an unpaid check advance from 5 years ago. The SOL in that state was 3 years. Now that the military moved us to a state with a SOL of 6 years they are threatening to sue. The problem is that I paid this debt 2 years ago and after 2 moves I lost the paid in full. I also am still a legal resident I believe of the first state wih the shorter SOL. I still pay their state taxes. Maybe I was scammed 2 years ago into paying but shoudn't the SOL apply to the state I pay taxes to?
