Can't connect Wiimote on latest build of Dolphin?

[Glitcher]

Hi, I've previously been using Dolphin 4.0-7052 and can run it without any major issues. Today I decided to upgrade to the latest build (8642) and discovered a peculiar flaw: Dolphin won't connect to my Wiimote Plus. I checked the settings: "Real Wiimote" for controller 1. I tried clicking Refresh and OK, but the emulator still won't connect to my Wiimote when I run a game. I pressed Alt+F5 a few times, but Dolphin keeps display "Wiimote Connected, Wiimote Disconnected" in sequence. I went back to build 7052 and could connect just fine with the same settings. Did something change in the latest build that prevents Wiimotes from connecting?
