MotionPlus worked at first but no longer...

[Mailman]

Hi,

I got an original Wii remote plus (meaning: built-in motion plus) and at first it worked perfectly. I used the Toshiba bluetooth stack to connect it and I was able to play games that need Motion Plus like Wii Sports Resort and Zelda - Skyward Sword.
However, suddenly bot games tell me that I need to attach the Motion Plus (hardware) add-on. Meaning, the games do not detect the built-in Motion Plus anymore.

Any ideas?
