Game won't open after deleting and redownloading

[legit_name]

I had the game on ASIA server for a few months, and loved it, but one day it stopped opening after the news section when I pressed play, so I thought to delete then redownload the app. I deleted it, then redownloaded it, but it seemed I accidentally downloaded the NA version. When I deleted the NA and redownloaded from ASIA, the file says asia but the game opens on NA server, in which I cannot log in. Therefore I deleted every file related to World of Warship, searching with 'World of Warships', 'Worldofwarships' , 'World_of_warships' and 'WOWS'. I redownloaded the game from ASIA, but when I try to open it, a menu saying 'shutting down' pops up for a moment then it closes, along with the WOWS on the dock. I have deleted the app and the dmg file, and re downloaded them several times, but every time it is the same. I want to know what files to delete to restart as if I am downloading the game new, or how to delete any cache I have from this game. I am on Mac OS X.
