Hacking Problem with DKCR

[horizon42]

I've got a problem with donkey kong country returns (pal).
I can play the first level, but than instead of getting to the next level, there is just the load screen for several minutes (donkey kong and diddy kong running through the jungle). Also if i load that save game again, there is just the load screen (clouds). What could the problem be and how can i get DKCR work?

PAL Wii 4.2e (3 Years old)

Thanks for help
