Ongoing issues with NSMB

I am having a problem playing NSMB on my wii. My specs are: usa wii with 3.2u with a wiikey 2 modchip. The game errors out after 5 mins. I have checked my burn settings and they are good. Is there a solution to this problem. i have read some threads but it still seems confusing. Can anyone give me a clear cut way of playing this game. The copy i have is unpatched. Thanks

go to wiikey.cn and download the usa 1.3 wiikey update and then burn it and load it. follow the instructions afterwards.

Thanks,,,, installed the mod update and works like a charm!!!!!!!!!!
