Hello!

I've bought Rayman 2 here with intention to play it on my Windows 7. But I have a problem with it: the game starts normally and the language menu appears but I can't select any language, the game does not respond to my keyboard or controller. What's the solution to that? Can anybody help?

That's really odd. You can try the controller fix to see if that'll work with your controller. My program, Rayman Control Panel, also allows to remap the buttons, so maybe that'll help? I've never heard of this issue before.
