    Redemption Code will not work

    Bodhie Long

      I ordered Fundamentals of Engineering Thermodynamics, 9th edition with a WileyPlus access code through Amazon. The code it came with was unopened, until i pulled the tab. I have been trying to access the online version of the text, but BookShelf continues to tell me my code has already been used. How can I fix this problem?
