[CLIENT] Weird client issue? Updated to the old league client???

I have recently gotten a small update to the league client (I was already on patch 6.17), it was a small file or too that went by quick. After it was done loading, my league client changed to a different format/design. From the new format, it has changed to the older league interface (including the login screen, but the theme is just black). And from this; I cannot access hextech crafting, notifications, chats, groups etc. Although, I am able to access the summoner profile and store.

I just want the old client back, and I am curious on how this even happened. If anyone can give me some feedback to a solution/answer that would be appreciated.
