I lost security code to power saves action replay

I had bought a power saves action replay for wii and i downloaded the disc and used it and it worked fine. but i got a new computer and i needed to redownload the disc and after i did that i needed the security code. one of my familymembers threw it away and i cant use the disc anymore. would it be possible to get a new code or send the disc and card back and get a new one? my disc and card still work its just i dont have the code.
