Can not load into games recently.

So I get into champ select and everything is fine, but after everyone was done choosing their champions and we were about to go into the loading screen, I was IMMEDITALLY kicked out of the game, and was told to reconnect. The game I played just before didn't do this, so this was sudden. That game, I was demoted and could no longer get loot. I try repatching, troubleshooting, closing out the client, turning off my computer until the next day; nothing worked. I now have 10 low priority queues and about to demote again. Help. Me. Please.
