Unexpected Login to the Client - Fix

Had this issue similar to everyone else, Looks like the login on the new Riot is glitching out.

Fix: I have a 2nd hard drive, which I re-downloaded league on, I didn't need to patch it, just needed to get back into the login page. Once I managed to do that, closed it and went back to the original hard drive with the original league and it proceeded to work. I believe the client was unable to login from that first page, so I would recommend not to do automatic sign in until Riot fixes.

Hope this helps.
