Beta Client- Won't Go to Login Page After Update

I updated my client today, and I was super excited to use it as my friends have started using it with no problem. So I updated with no problem, and I then clicked launched. I waited for a few minutes, thinking it might take a while as this was the first time I've used it since it updating. Nothing showed up. I then decided to click on the League of Legends symbol on my desktop, and it got to the patcher screen, same as before the update (not sure if it changes), and I clicked launch again. I then received a prompt saying that another version of League was already running. When this happened, a black box appeared in the top left corner of my computer screen, and on my taskbar it was the new client.

Any ideas or thoughts on how I could fix this?

Thank you for your time and your help,
