Cant Update/Play League. (Unspecified error occurred. Please check the logs for more information.)

So Today as I updated my league, my pc crash and now my league isn't working. Its giving me the error: Unspecified error occurred. Please check the logs for more information. Ive deleted my project's folder and the lol_air_game_client or whatever 4 times at least. I just wanna play this game :( I don't want to reinstall. On my old pc I would have to keep reinstalling each update because of errors and such.
