Bought NIS for 3 pcs but it only allowed me one

I bought the Norton Internet Security and it allowed me to put it on 3 computers but when I tried to entering the product key on the 2nd computer is said that I exceeded the number of allowable installations, even though I only had it on one computer. How can I fix this problem?
