I had my wii successfully hacked for quite a while now but recently i am having trouble.

I am having major trouble. I start up the Wii fine and remotes connect and work fine but whenever I start up USB Loader or Homebrew Channel my remotes disconnect and will not reconnect and for a while the lights on the remote dont even flash!?!?
I have checked the sensor and it is not remote batteries

Please help I dont know what to do I have check other forums :/
