Black Screen after Logging

After the last update of 11th Feb and today’s update ,when i lunch the client i get the characters window then when i choose one and login i get a black screen and the 'loading resources" circle keeps tuning but nothing happens

i tried cleaning the cache and verifying the files using the tool and nothing,please help it’s been two days
