League won't reconnect to game

I've recently started up a game of League and It seems I can't play. The launcher works fine but when I try to reconnect to game, It just closes the launcher and nothing happens. I've tried reconnecting to game around 10 times now and nothing still happens. I recently had problem with my LoL launcher not working too, I fixed it by deleting everything in the RADS folder, How do I fix this?
