Have u tried changing the user.ini??
In most games u can change Users/Logins/Keys/Options in this..
This is from my Brink, But I know "Witcher 2" has the same user.ini..Since I Installed a repack
In User.ini (located in My Documents) under the section Input QWERTY or whatever keyboard layout you have:
Assign keys you want to the bold part above!
After that make sure you change any existing entries for IK_Up, IK_Down etc. or whatever keys you used for above in any other places.. Simply just make sure the keys u used are not repeated in other places!
Hope it works!
tried it bro, left and right works, but still Up arrow and Down arrow not working.. Im trying 1.2 patch, sm ppl say it works.. sm ppl say its not. thanks macho
