League Of Legends Not Working

So I logged on and went into a rank game.. I went Mid/Sup then got into the game. I was 3rd pick so I had first ban. After Banning period was over I waited until it was my turn. Then I chose nami since I got support. I tried locking in and it didnt work. I kept pressing the lock in button and the timer went up. It's still on my screen and I thought it would MAKE me dodge and I was in my promos. Then someone in the chat said "what the heck is this" so by their reaction i thought that it wasn't just me that's seeing this. So the group disbanded right after that and then I tried going on my profile to check if it gave me a loss on my promotion but an error message came up like 10 times and I decided to exit out and log back in. I logged back in and now I can't even go online and it says "Log in Error" um.. help?
