Client getting rejected by the server

So like everybody else I updated LOL to its current patch 6.3 this morning. But after the patch when I tried to login I got an error saying "CLIENT VERSION 6.2.16_01_27_16_56 IS REJECTED BY SERVER". I tried to relogin a couple of times but getting the same error. HELP!!!!{{item:3070}} {{item:3070}} {{item:3070}}
