Rayman Pirate-Community

I recently downloaded Rayman 2 on the pc.
It took me quite a while to get it to work on fullscreen, but eventually I did it!
Now I thought that all my problems would be solved, and I could finally enjoy Rayman 2.
Little did I know, I was very wrong.
It's a very, very, weird bug. I don't see Rayman's fists properly, nor the lums. They all are giant pixel blocks.
The rest of the game works fine graphic wise. The weird thing is, that in the very first room. Where Globox gives you your power back, I can see the Rayman's fists properly. But the minute I break through the door to slide down, they transform in giant pixel blocks.
Does anyone have an idea what could be wrong, and how to fix it?

Thanks in advance!

I had similar problems with my older CD copy of Rayman 2, the disc was pretty scratched up though. It might just be that you've got a corrupt copy of the game.
