Dolphin not detecting controller inputs?

[gingerburnin]

I recently downloaded dolphin to play smash. I'm using a mayflash adapter to connect my gamecube controller. I mapped the the gamecube controls and the controller was working fine all inputs were working. Recently though my inputs are not going through, i haven't changed anything. even when i try to remap the controls it does not work. I have tried two different controllers in all ports of the mayflash adapter. Any ideas for how to fix it?
