Sound is broken(complicated situation)

I'm having problems with in-game sound.It's a complicated situation but i'll try to explain. I was moving my games in my hard disk and i accidentally split League of legends files in two(Leaving 1 part of the game in one directory and the other part in another). When I entered the LoL client it prompted me to repair my files because of possible corruption and so i did.

It didn't really help me.Then i figured out my mistake and merged the two halves back together.The game is now working fine but I'm having sound problems. Basically most of the sound effects are missing. For example i can hear the music and the minion attacks but i can't hear champion autoattacks,some abilites and so on.

I think this may be fixed if you provided me with some kind of a download to the sound files of the current patch.

Sorry for my bad English and thanks in advance.
