Download 4.2.3 isn't working

I started the downlaod but for some reason it doesn't downlaod . It is stuk on 0% for like a hour . What do I do?

There's a lot of reasons why this is happening, it might be a problem with your internet or you might have paused the download by accident. Try one of the mirror links instead.

ok got it . and p.s is there a way to decrease the volume a bit? I normally watch youtube while playing pokemon but i can't hear the video because the game is to loud .

just use yor windows mixer or mute the bgm with f1
