i downloaded the US client thinking it was EU client, and after 6 hrs waiting for the download to finish i realized i downloaded the wrong client

is there a way to play EU servers without having to re-download everything again? like downloading a small sized file that would switch it to be EU client? i dunno please help? >_<

You'll need to download the correct client. Changing the files can cause problems with the client afaik.
