Game Won't Load After Last Patch

I have to try to load the game 4-5 times, sometimes more, to get into a game. Furthermore, I can't spectate games at all anymore. I tried downloading the Hextech Repair tool, and the thing won't even run, let alone give me an error message. Sooo... the game takes multiple tries to load, and the repair tool that exists for the purpose of fixing errors like this needs a repair tool of its own.

My OS is clean, and my PC is able to run literally anything else without any issues. This has only been happening since the last patch went live. Anyone else experiencing the same issues?
